Introduction to Map and Compass Outing September 26, 2009

Join the REI Outdoor School for an instructional hike to Sentinel/Taft Dome in spectacular Yosemite National Park to learn how to use a compass and read a map to truly find your way in the wilderness. We'll teach you the parts of a compass and how to make use of them. We'll talk about magnetic north, true north, and magnetic variation (declination), and help you make sense of it all. Then we'll learn how to take a bearing from the terrain, and from your map, so you can triangulate your position and plan a route. Speaking of maps, what do all those squiggly lines mean? We'll look at topographic maps and learn how to read them to understand your terrain. We'll also discuss strategies such as using "handrails" for "aiming off' to improve the accuracy of your backcountry navigation. Map and Compass Basics Class is recommended (but not mandatory) to get the most from this outing. Advance registration is required. Contact any Sierra area REI store. Member: $45.00, Non Member: $65.00
