This story has several origins, two of which are worth mentioning. The first one jumps out while looking at a map of Rocky Mountain National Park, where the lower third of the Park east of the Continental Divide consists of Wild Basin, the watershed of the North St. Vrain River. This 70-square-mile arena is ringed by high peaks on three sides, circling from Mt. Meeker and Longs Peak in the north to Ogalalla Peak and Elk Tooth in the south, all connected by a high continuous ridge. It would be impossible to design a more imposing and tantalizing closed-loop ridge run than the circumnavigation of Wild Basin.
