Lost Lakes-Devils Causeway

Lost Lakes-Devils Causeway Professional Review and Guide

"Hikers are often surprised when they first see the Flat Top Mountains of northern Colorado. Most of the state’s other prominent mountain ranges are crowned with rugged peaks of Precambrian granite, gneiss and schist. In contrast, the crest of the Flat Tops runs across an enormous plateau of flat basaltic lava.

The vast tableland occupies an area of about 500 square miles, with a large fraction of it being above timberline. The ancient lava flow that covered the Flat Tops was laid down over the top of an older sedimentary formation, and today the boundaries of the lava are often defined by steeply eroded cliffs of rusty red shale and alluvium."
