Survival Stories

1. Survival Against the Odds
Sir Ernest Shackleton’s Antarctic expedition of 1914 would ultimately fail, but the hardy crew he mustered would still win honour and recognition for its ability to survive against the odds.
After their ship Endurance was crushed in pack ice, the crew abandoned the plan to cross Antarctica on foot and the aim became merely to survive. Over two years, Shackleton led the crew across ice floes, then in lifeboats to a camp on Elephant Island where for six months the main group would subsist on seal meat and blubber.
Shackleton took five men around the island to the north and then across 800 miles of treacherous ocean to South Georgia Island. He then hiked with two others for 36 hours across the island’s uncharted interior to a whaling station with another three months to go before he could safely reach the crew left on Elephant Island.
He later wrote, “We had suffered, starved and triumphed, grovelled down yet grasped at glory… We had reached the naked soul of man.”
 
2.Lost in the Amazon
“I was obsessed with the idea of exploration,” Yossi Ghinsberg told CNN Traveller magazine on the recent release of his book Lost in the Jungle: A Harrowing True Story of Adventure and Survival.
It describes how in 1981, Israeli-born Ghinsberg and three companions set off into the depths of the Bolivian Amazon. When they realized they were ill-equipped for the journey, and lost, the four broke off into pairs; two were never seen again.
Ghinsberg and his friend Kevin were to float a raft downriver, but it caught on a rock and they were split up. For 19 days, Ghinsberg wandered helplessly in a brutal environment.
Fortunately, some local men had found Kevin and helped him search the river for Ghinsberg. Miraculously, they discovered him, alive and with a new understanding of his weaknesses and strengths.

 
3. Two Weeks in an Ice Cave
In 1982, Mark Inglis and Phil Doole were high up the slopes of New Zealand’s highest mountain, Aoraki Mt. Cook, when a blizzard hit.
They built an ice cave and waited for the storm to pass, but it would be 13 days before help could reach them. They survived on meagre rations, but in the cramped cave they lost circulation in their legs, which had to be amputated.
This hasn’t stopped the men’s climbing careers. Both have gone on to summit Mt. Cook, and in 2006, Inglis became the first double amputee to conquer Mt Everest, losing five fingertips and more flesh off his legs to frostbite, though none of his strength of character.
He told the New Zealand Herald, “When you lose your legs when you’re 23… something like this is just a minor hiccup, just a bump in the journey, really.”
 
4. Stranded in the Andes
It’s a story so extraordinary it has spawned several books, a Hollywood film, an acclaimed documentary and an official website, and can be recognized with just one word: Alive.
When the plane carrying a Uruguayan rugby team crashed in the Andes in October 1972, the story should have ended there, but it was only just beginning. Of the 45 people on board, 12 died in the crash or shortly afterward, another five passed away the next morning from injuries, another on the eighth day, then eight in a later avalanche.
The remaining 16 struggled through extreme cold and starvation before resorting to cannibalism of those who had perished.
When it became clear help wouldn’t come to them, Nando Parrado and Roberto Canessa hiked for days out of the mountains and eventually found help. The most recent, and arguably the most sensitive retelling of the 72-day saga is Gonzalo Arijón’s 2007 documentary, Stranded: I Have Come From a Plane That Crashed on the Mountains.
 
5. Stuck Between a Rock and a Hard Place
Amputating your arm with a blunt knife is a task the average person would find virtually inconceivable. But on May 1, 2003, it was the only option left to Aron Ralston after an 800-pound boulder fell on his arm, pinning it to a canyon wall.
After five days, the little food and water he had was gone and it was unlikely anyone would find him in the remote canyon in Utah.
In his book, Between a Rock and a Hard Place, he describes how he managed to literally break free, first using the boulder to leverage his arm until the bones snapped and then sawing away at muscle and tendon with his pocket knife. He then had to rappel down a 65-foot wall. He was walking back to his car when hikers found him.
The 33-year-old continues to climb, including all of Colorado’s 55 peaks higher than 14,000 feet, and is also a motivational speaker.

 
6. Mountain Odyssey
Joe Simpson and Simon Yates were descending from the summit of the 20,813-foot-high Siula Grande in the Peruvian Andes when disaster struck-twice. First, Simpson slipped and broke his leg. Then, while Yates was lowering him down, Simpson went over a cliff and was left dangling on the end of the rope.
Yates couldn’t see or hear Simpson and held on for an hour as he was pulled down the mountain.
Controversially, he cut the rope (which some say was against the mountaineering code, while others say it ultimately saved both men’s lives) and safely descended. Simpson dropped into a crevasse, and though severely injured, was able to abseil down to the bottom from the ice shelf he landed on. From here, he spent three days dragging himself across five miles of rough terrain, with no food or water and in great pain.
He crawled into base camp in the middle of the night and was reunited with Yates, who, after recovering from his own injuries, was planning to break camp the next morning. The harrowing tale of survival is told in detail in Simpson’s book, Touching the Void, and the documentary of the same name.
 
7. Struck Down in the Pacific
Sailing the South Pacific may seem like an idyllic pursuit, but when American Tami Oldham Ashcraft and her British boyfriend Richard Sharp were caught in a category four hurricane 19 days into what should have been a 30-day crossing, the dream turned into a nightmare.
It was 1983 and they were en route from Tahiti to San Diego to deliver the 44-foot sailboat Hazana. Battered by Hurricane Raymond’s 50-foot waves, Hazana capsized. Ashcraft, sheltering below decks, was knocked unconscious. When she woke 27 hours later, Sharp was gone, his safety line broken, and while the boat had righted itself, the mainmast had snapped.
In the May 2002 issue of National Geographic Adventure, Ashcraft described how she had to fight the desire to just give up, how she fixed a makeshift mast and sail, rationed her supplies and plotted a course for Hawaii, 1,500 miles away.
Forty days later she sailed into Hilo Harbor, still in shock but thankful to be alive. She continues to sail and in 2000 published an account of her ordeal in the book, Red Sky in Mourning.
 
8. Three Months in the Outback
When a walking skeleton over six feet tall appeared in front of his jeep in April 2006, Mark Clifford, a farm manager on a remote property in Australia’s Northern Territory, must have thought he was seeing things. The skeleton was 35-year-old Ricky Megee, who had been lost in the outback for an incredible 10 weeks.
Apparently drugged and left for dead by a hitch-hiker he had picked up (though he also claimed his car had broken down), Megee survived by staying close to a dam and eating leeches, grasshoppers, and frogs.
While police and the public had doubts about the story, especially when it came to light that Megee had minor drug convictions, there’s no question he was lost in the outback, for whatever reason, and lucky to have survived.

Active Feet
Active navigation route of travel.

Almanac Data
Data sent through the GPS satellites, including satellite orbit position, cluster, and other information. Almanac data increase the search speed satellite by the GPS receiver.

Anti Spoofing
To prevent the acceptance and use of code-P by a third party in the wrong way to send information through the P-code modulated. United States Defense Department from receiving such information.

Auto Clock
Is a precision clock that uses sesium or element rubidium. Error margin is estimated to be one second for every million years.

Beacon
Nondirectional transmission station is mounted to improve the accuracy of GPS positioning. Used to calibrate the GPS pseudo distance, where the transmission station is located. If the GPS receiver located in the area that can receive and utilize this data, the positioning accuracy can be improved.

Coarse Acquisition Code (Code C / A)
GPS Satellite emit a standard position signal for use by the public. These include the time and positioning information to GPS receivers value is accurate to about 100m.

Normal Initiation    
A GPS receiver must execute a series of tasks at the time of initiation system initialization, for example downloading almanac data. This process is also called initialization .

Control Segment

Faithful Friend of Your Trip

What would the goods that must be taken if you intend to travel, away from home? Perhaps you will say, any item required, just come to the nearest store and buy it. However, it turns out in certain situations, money can not be a major rescue you, especially if the goods you are referring to are not available in the goal area. 
Well, to anticipate the crucial issues on the trip, should provide the following items in your gift bag or suitcase :
  1. Identity cards (Students Card, Passports, etc.) Always take it you need to remember the raids are often held by local authorities and identification card shall be requested by the hotel or rental car. If necessary, keep a photocopy or scan in your e-mail as a backup when things happen that are not desired (such as loss).
  2. Money in cash for emergency purposes. Put in a special place, such as secret pockets in clothing or bag. Reserve money is very helpful when a credit card can not be used or ATM can not be found.
  3. Hats, sunglasses, and sunscreen to protect you from hot sun.
  4. Shoes and flip flops are strong and comfortable to wear for your walk route crashing.
  5. The key and padlock for your bag, to avoid the hands of ignorant who intend to take your valuables on the trip.
  6. Bag for transporting empty souvenirs you buy on the trip.
  7. Earplugs are very useful when you want peace without interference annoying noises.
  8. Dental floss, bandages, and shaving cream; personal equipment that should not be left behind to make sure your appearance still excellent during the trip.
  9. Waterproof jacket, to deal with heavy rain that often comes suddenly.
  10. Anti-mosquito lotion, protect you from bites that often can cause malaria or dengue fever.
  11. Blankets to warm up your night sleep.
  12. Another important thing is to keep thinking positive and always happy throughout the trip. Bring your MP3 player, crossword, cameras and even the books of humor to relieve boredom on the trip. Put your smile always to brighten your days away from home.

The journey had been prepared and was ready to step foot to explore the archipelago. Let's go!

Garmin Colorado 400t

Garmin Colorado 400t
Garmin's Colorado is a rugged, waterproof outdoor handheld GPS that can be used for hiking, boating, camping, in the car, or Geocaching.
Available in 4 different versions, the Colorado 400-series sports an innovative scroll wheel joystick controller, is the first GPS to support Whereigo ("Where I Go"), Groundspeak's newest twist on Geocaching (think virtual scavenger-hunt meets Geocaching), ships preloaded with World Base Maps in shaded relief, has a digital compass and altimeter, and can be paired with a heart rate monitor and/or speed and cadence sensor for fitness use.
GPSmagazine puts the Colorado 400t through its paces, and finds out if Garmin's newest handheld is worth the $599 sticker price.

1. Colorado: One GPS, Many Maps

Garmin offers four Colorado models to choose from:
Features 300 400i 400c 400t
World Base Map Yes (DEM*) Yes (Satellite) Yes (Satellite) Yes (DEM*)
U.S. Inland Lakes Mapping Optional Yes Optional Optional
U.S. Bluechart Mapping Optional Optional Yes Optional
U.S. TOPO Mapping Optional Optional Optional Yes
Price $499 $599 $599 $599
* Digital Elevation Model
All 4 Colorado models are identical in terms of hardware, and all three 400-series models have the same retail price of $599, while the 300 model retails for $499.
The 300 and 400t include the "Digital Elevation Model" (shaded relief) World Base Map. Garmin believes the Colorado is the first outdoor handheld GPS to use this level of resolution. The 400t version comes with built-in TOPO maps for the U.S., and includes a detailed 3D elevation perspective (looks almost like a photograph).
The 400c version is geared towards boating, and ships with coastal waters maps for the coastal U.S. and Bahamas. The 400i comes with maps of inland, lakes, and navigable rivers.
All four Colorado models can be upgraded to use additional maps. The Colorado has 3GB of internal memory, but there's only about 120MB of unused space, so you'll need to buy an SD memory card if you plan to use additional maps.
Garmin's additional maps are available on DVD and can be transferred to the Colorado via a PC, and Garmin also sells maps on SD cards ready for use in their GPS units. Additional maps range in price from $29 to $299, depending on the map and coverage area, and are available via Garmin's website and other online retailers.

3. Colorado Overview

Garmin Colorado, Front
Figure 1: Garmin Colorado, Front

The Colorado feels extremely well built and sits nicely in the palm of your hand. The unit is constructed of matt finished metal and is framed by a thick rubber material that protects the unit from getting scuffed during outdoor use, and also helps keep water/dust/etc. out of the sensitive areas. Note that the Colorado is waterproof rated to IPX7 (can be submerged in water).
The large, 1.53" x 2.55" (3-inches diagonally measured) backlit color TFT display occupies almost all available surface area. Compared with other Garmin handhelds, the Colorado has a larger display.
An innovative scroll wheel / joystick (Garmin calls this the Rock 'n Roller) sits at the top of the unit, and is flanked by left and right soft keys.
The antenna is quite short, making it easy to cary the Colorado in your pocket.
Garmin Colorado, Rear

Figure 8: Installing the Batteries

The Colorado takes two AA batteries. Battery life on the Colorado is excellent - up to 16 hours if you're using lithium batteries.
SD Memory Card Slot
Figure 9: Colorado's SD Card Slot

The SD data card slot is located on the bottom of the unit, as shown above. Note that the SD slot is only accessible when the protective battery cover is removed; during normal use the SD slot is protected from water, dust, etc.
Garmin sells additional maps on SD data cards, or you can use your own data card and purchase Garmin's maps on DVD and transfer the maps via a PC.
SD cards can also be used to store images, which can be then be viewed using Colorado's included Image Viewer.
Rock 'N Roller
Figure 10: Using the Rock 'N Roller

Garmin calls Colorado's scroll-wheel/joystick combo controller the Rock 'n Roller. Designed for easy one-handed use, the Rock 'n Roller rotates clockwise and counter-clockwise, and can be used to navigate menus and lists on the Colorado and zoom in or out on the map. The button in the center of the thumb wheel is the enter key. Pan the map or highlight a menu item by pressing up, down, left, or right.
This new controller is a major improvement over previous Garmin handhelds and a welcome enhancement.

  • Recreational
  • Geocaching
  • Automotive
  • Marine
  • Fitness
Depending on the profile, Colorado changes various settings and available options to suit the intended use. For example, in Geocaching mode the Colorado displays TOPO maps and has a dedicated Geocaching icon on the Where to? menu. When set to Automotive mode, however, the maps change to display roads instead of trails, and directions are displayed in turn-by-turn style.
 
Additional profiles can also be created to suit your own particular preferences.Waypoints
Figure 16: Waypoints

Waypoints are locations you want to save for future use, or to share with others. To mark a waypoint on the Colorado, rotate the Rock 'n Roller wheel from the Shortcuts menu and select Mark Waypoint, as shown above.
Marking a Waypoint
Figure 17: Saving a Waypoint

The Colorado automatically assigns waypoints a three-digit number. This can later be changed to a name of your choosing.
A handy shortcut to saving a waypoint is to press and hold the enter button.

5. Navigating to a Destination

Where To? Menu
Figure18: Where To? Menu

You can enter a destination address either via the Where To? icon, shown above, or by choosing a point on the map.

Preferred Search Category
Figure 19: Preferred Search Category

Choosing Where To? from the Shortcuts menu brings up the search category menu, shown above.
Different destination types are available depending on the current profile, or mode, the GPS is operating in. For example, in Geocaching mode there's an option for choosing a Geocache as a destination. The following destination types are available from the Where To? menu:
  • Recent Finds - displays a list of recently found destinations
  • Waypoints - displays a list of waypoints stored on the Colorado
  • Tracks - displays a list of tracks stored on the Colorado
  • Geocaches - displays a list of downloaded geocaches (from geocaching.com)
  • Routes - displays a list of routes stored on the Colorado
  • All POI - displays a list of Points of Interest

7. Geocaching

Geocaching with the Colorado
Geocaching is a high-tech treasure hunting game that has gained popularity over the past few years and combines outdoor activities with GPS adventure. Geocachers seek hidden "treasures" using GPS coordinates posted on the Internet by those hiding the geocache. You then use a GPS to go and find the treasure, sign the log book, and possibly retrieve some small price and deposit a small prize in return.
Geocaching is a wonderful activity that combines high-tech with outdoor activity, and exposes you to new trails/places you might not have otherwise discovered. It may not sound like much of a challenge to find hidden treasure if you know the exact coordinates, but it's more challenging than one might assume.
Using the Colorado for Geocaching is a bit like using a cannon to kill a fly; with so many advanced features available, the biggest challenge is keeping all the options straight and figuring out how to use only the features you need.
Garmin's Communicator Plugin
Figure 24: Garmin's Communicator Plugin

Transferring Geocaches to a GPS can be a tedious, time consuming task. Thankfully, Garmin has developed a browser plugin that makes it possible to transfer Geocaches from geocaching.com directly on to the Colorado and other Garmin GPS units. It's not required to use the plugin, but it sure makes life easier. The plugin is available for Mac or PC, works in IE or Firefox, and can is a free download via Garmin's website.
Installing Garmin's Communicator Plugin
Figure 25: Installing Garmin's Communicator Plugin

Installing the Communicator Plugin is easy and takes about a minute to complete. No reboot is required, although you do need to quit all running browser windows for the installer to work.
Download to GPS Icon
Figure 26: Download to GPS Icon

Once the plugin has been installed, connect the Colorado to the computer via the included USB cable, and Geocaches can be transferred to the Colorado by clicking on the "Transfer to GPS" icon, shown above.
Another advantage of using Garmin's plugin to upload geocaches to the Colorado is that all accompanying data is also transferred, including a detailed description of the cache, hints, and more, effectively making Geocaching a paperless activity since you no longer need to bring printouts of the geocache from geocaching.com.
Geocaches can also be manually entered into the Colorado, if desired.
Once the Geocaches have been transferred to the Colorado, they are accessed by selecting Shortcuts > Others > Geocaches(if you're in Geocaching mode, Geocaches also appears directly on the Shortcuts menu).
Geocache Page
Figure 27: Geocache Page

After choosing a preferred geocache from the list of available caches, the Geocache Page appears, shown above. In my testing I found that most geocaches didn't transfer over to the Colorado with all the available information. For example, the Geocache shown above in figure 27 includes basic information like the cache name and coordinates, but some other caches include difficulty and terrain ratings, the cache size, and a detailed description of the cache.
I'm not sure if this is a bug with the pre-release version of the Colorado I tested, an issue with the browser plugin, an issue with the caches I tried to transfer, or a combination of issues.
Compass
Figure 28: Compass

When navigating to a destination, the Compass page guides you to your target with a graphic compass display using a red pointer, as shown above.
I had to calibrate the compass before the red arrow would appear. Calibration is simple and easy: the Colorado prompts you to turn clockwise slowly in two full circles until the compass is calibrated. Move too quickly and the Colorado instructs you to slow down. Once calibrated, the red arrow appeared on the compass screen and directed me towards the destination. The manual says you may need to re-calibrate the compass if the GPS is moved long distances or subjected to sudden temperature changes, or after the batteries have been changed.
The compass ring displays your heading and the pointer shows what direction you should be headed. Speed, distance to next turn, ETA, and remaining time are also displayed on this page.
Trip Computer
Figure 29: Trip Computer

The trip computer is available is Automotive or Recreational mode, and displays various statistics regarding the current trip, such as current speed, average speed, maximum speed, trip odometer, and more.
The trip computer page can be customized and has the following settings available:
  • Reset - Reset the trip data
  • Big Numbers/Small Numbers - view fewer/more fields with larger or smaller numbers
  • Change Data Fields - choose which data you want to display on this screen
  • Restore Defaults - reset the data fields to the factory default settings

8. Whereigo ("Where I go")

Whereigo
Colorado is the first GPS I've seen that's compatible with Whereigo gameplay. Whereigo (pronounced "where I go") is a new location-based adventure game invented by Groundspeak, and combines Geocaching with role-based characters, puzzle solving, and elaborate story lines.
By combining virtual and real-world elements, Whereigo aims to bring geocaching to the next level by creating an outdoor adventure game in which a GPS is used to guide you to physical locations and you interact with virtual objects and characters. More detailed information on Whereigo'ing is available at www.whereigo.com.
Whereigo games are called "cartridges", and must be downloaded onto the Colorado via a Mac or PC.
The Colorado includes a Whereigo tutorial that explains the basics. To access the Whereigo tutorial select Shortcuts > Others > Whereigo > Whereigo Tutorial.

9. Tracks

Whenever the Colorado is turned on and receiving GPS satellite signals, it is creating and storing track logs, which can be archived and shared with other users.
Using Tracks
Figure 30: Using Tracks

To use Tracks, select Shortcuts > Where To? > Tracks, as shown above in figure 30.
Tracks Page
Figure 31: Tracks Page

After choosing Tracks from the Where To? menu, archived and loaded Tracks are listed.
Viewing a Track on the Map
Figure 32: Viewing a Track on the Map

Tracks can be viewed on the map, elevation profiles can be viewed, or the track can be navigated by choosing Go.
To archive the current route for future use or sharing with other users, press the left soft key for Options > Archive.

10. Others

Despite it's confusing name, the Others menu is home to several important features on the Colorado, including the wireless sharing feature, a 3D map view, sunrise and sunset times, hunting & fishing information, and more.
Accessing the Others Menu
Figure 33: Accessing the Others Menu

Like most everything else on the Colorado, the Others menu is accessed via the Shortcuts menu.
It can be confusing knowing what applications are located on the Shortcuts menu and which ones are accessible via the Others menu. Depending on the active profile, applications may move from one menu to the other. Note that when an application is added to the Shortcuts menu, it is removed from the Others menu.

13. Conclusion

Colorado is Garmin's newest handheld outdoor GPS aimed at outdoor, marine, and fitness enthusiasts. Available in 4 versions, the 400t model includes 3D elevation perspective and ships preloaded with U.S. topographic maps. Additional maps can be purchased from Garmin. Colorado is also the first GPS to support Whereigo ("where I go"), groundspeak's newest GPS-based activity (the same folks who made geocaching popular).
Colorado's use of profiles makes it easy to switch the GPS from automotive to marine, recreation, fitness, or geocaching mode, automatically re-configuring the menus so that the handheld is optimized for the chosen activity. Colorado supports paperless geocaching, displaying all relevant information about a given geocache so that you can leave the printout at home.
The Colorado weighs 7.3 ounces, runs up to 15 hours on two AA batteries, includes an electronic compass, barometric altimeter, and has an SD slot for loading additional maps. The Colorado displays air temperature, and can be paired with a heart rate monitor and/or speed and cadence sensor for fitness training.
With a suggested retail price of $599, the Colorado 400t isn't cheap. But it performs extremely well and is ideally suited to the outdoor enthusiast looking to buy one GPS that serves many purposes. The Colorado is a major upgrade from previous Garmin handhelds, and is significantly easier to use than Garmin's GPSMAP 60csx.
The Colorado uses Garmin's own GPS receiver instead of SiRF's high performance StarIII receiver. In side-by-side comparison testing, the Colorado performed identically to the SiRF-equipped Garmin GPSMAP 60csx, quickly locking on to satellite signals and maintaining solid reception.
Handheld units are still harder to use than models designed primarily for in-car use, like Garmin's popular nuvi models. But they're also much more versatile and capable devices, and it's well worth the effort it takes to learn how to fully use the Colorado. Those already familiar with handheld GPS units will find Colorado easy to use and extremely powerful.
Those looking to replace their in-car or boating GPS will want to invest in additional, more detailed maps from Garmin, as only the base and topo maps are included on the 400t.
Overall there's very little to complain about on the Colorado 400t. Well built and easier to use than previous models, Colorado raises the bar on what to expect from a handheld GPS.
