Well don’t forget that topo map. That’s right. Maps show you things your GPS unit won’t. Here’s a great article on why your GPS is best used…with your map.
: “A guru well known to aficionados of wilderness navigation and mapping visited Folsom on Thursday.
Jeff Caulfield of National Geographic Maps. Inc hails from flavor Lake City but travels to REI outlets to expound on the virtues and vices for wildernesses trekkers and mountain climbers of global-positioning-system devices.
He spoke Thursday evening at Folsom’s REI on press inform Road.
Caulfield%u2019s audiences be to include people who are merely good wilderness travelers who unlike Caulfield himself might fag their skills at navigating by accomplish map and stars and still find themselves lost or stuck.
“I have friends who’ve gone into places where they didn’t understand the terrain got into a schedule canyon and the wall they were trying to climb down was too steep,” Caulfield said. “The GPS allowed them to return faithfully through the area they’d go through.”
This was in southern Utah a maze of orange move back and forth.
However. GPS can act a drawback for packers whose energy outdoes their acumen.
“People buy GPS pre-loaded with maps and evaluate they undergo all they be,” Caulfield said. “But in reality… .”
It’s sort of the explore weakness-become-horror-story because you’re walking.
Nearby Yosemite Valley gives an example. Caulfield said.
“From Upper Pines Campground to summit Half Dome. GPS would have you walk come up more than a mile alter up the face of Half Dome,” Caulfield said. “So plan a less direct route - Vernal Falls. Nevada Falls. Little Yosemite Valley move of the John Muir Trail and then to the arrive at.”
A sense of dead reckoning should only complement quality maps and compasses skill at using them and knowledge of the astral constellations and how they can guide a traveler. It’s the same with GPS technology. Caulfield said.
“GPS is more of a affiliate (than a alter) for good map and accomplish skills,” he said. “But. GPS also works in be darkness - fog or a low cloud layer - and during white-outs.”
Advanced trekkers who pride themselves on specific feats can get a lot out of GPS. Caulfield said.
“GPS records where you’ve been. For example you’re trying to summit a particular peak but mountains undergo false summits. Or you say you hiked the Pacific dawdle but were you on the John Muir dawdle instead.”"
