One of the toughest parts of doing any research is finding out what work has already been done. To help with future investigations into the canyon, we've assembled this library of canyon-related documents. The information collected below is intended to give some background on the canyon's history and ecology. (Be sure to also check the curriculum page and the list of senior thesis projects that have been done in the canyon.)
