This morning I outlined the plan of campaign for the third crew. Unlike all the other rotations, this crew has no one in it with extensive Devon Island field exploration experience. For us, as for a crew newly landed on Mars, the surrounding territory is terra incognita. We have aerial photographs and a topographic map, but they do not tell us what the land about us is really like, or what we can find there. So we must create a map with sensuous content. We must explore.
