YARMOUTH, Maine―Ed Viesturs, America's leading high-altitude mountaineer, will be relying on the DeLorme Earthmate(r) GPS PN-20 when he sets out this week on the 2008 Canadian Arctic Trek for Earth Health.

The PN-20 is a WAAS-enabled, bright-color-screen handheld receiver capable of displaying multiple map and imagery types.
 
Using data import and registration capabilities available in DeLorme's XMap(r) GIS software, the company's development team has customized the expedition's PN-20  receivers with high capacity SD Cards (SDHC) containing topographic detail maps and Landsat satellite imagery for the area the journey will cover.
 
This will be the second Arctic expedition in which Viesturs has used the PN-20. In 2007, he participated in polar explorer Will Steger's Global Warming 101 trek, a dog sled journey on Baffin Island to document how climate change is affecting the native Inuit population.

Viesturs said he was impressed with the PN-20's performance and simplicity of use, and was happy to be similarly outfitted for this year's expedition. Joining him will be John Stetson, a renowned arctic explorer and pre-eminent dog sled musher who will also be equipped with a PN-20. They will embark on a 150-mile ski journey across Baffin Island. The expedition's theme is Healthy Planet = Healthy People.

ABOUT THE 2008 CANADIAN ARCTIC TREK FOR EARTH HEALTH

On April 25, 2008 Ed Viesturs and John Stetson will travel to the Canadian Arctic to mount a sledge hauling ski journey through one of the most beautiful and pristine areas of Northern Baffin Island. The theme for this expedition is Healthy Planet= Healthy People. Their objective is twofold. First, to utilize and familiarize themselves with the equipment, systems, and strategy necessary for a possible future ski journey to the South Pole. Second, to showcase the effects of climate change already occurring in the Arctic regions. The expedition should last for approximately 20 days and Viesturs and Stetson plan to make daily progress reports via satellite telephone. Check www.edviesturs.com for the dispatches.
