The Hidden Truth Behind Horsetooth Reservoir’s Hidden Wonders Waiting to Be Seen Nestled just outside Fort Collins, Colorado, Horsetooth Reservoir is far more than a scenic stop for fishermen and kayakers. While its rugged cliffs and endless blue waters attract visitors year-round, few know that this reservoir harbors hidden wonders just waiting to be discovered.

From ancient geological secrets to unexpected cultural treasures, the reservoir reveals a rich tapestry of natural and human history waiting to shine. ### The Geological Secrets Beneath the Surface Horsetooth Reservoir was formed by the dramatic Horsetooth Dam, built in the 1940s to supply water to the expanding city.
