Wilderness: A Survival Adventure

Your small plane has crashed in the Sierra Nevada mountains. You are all alone in the snow and cold, but you manage to pull a topographic map from the wreckage of your plane. The map shows the location of a ranger outpost, your only hope for survival. But you could be anywhere on this map, an area “twice the size of the state of Delaware.” To survive, you must determine your location and hike to the safety of the outpost.
