Lost on Purpose is the nonfiction adventure narrative of a former technology executive who took leave of the real world to reinvent himself as a twenty-first century mountain man. In October-November 2013, Patrick Taylor crossed the Rocky Mountains alone on foot. He passed through one of the largest wilderness areas in the lower forty-eight to reach and retrace the route of Lewis and Clark in the winter. The sacrifices—vocationally, financially, emotionally—are measured against the benefits by the author in a refreshingly honest, humorous, and inspirational fashion.
