2019 Map of Lake San Cristobal

About this map

Lake San Cristobal dominates the upper portion of this quadrangle, formed by the massive Slumgullion Earthflow which famously dammed the Lake Fork river. This geological instability is further evidenced by the nearby Slumgullion Slide, creating a landscape defined by slow-moving earth and high-altitude water bodies. To the south, the Continental Divide National Scenic Trail winds through the high country along the border of the Gunnison National Forest and Rio Grande National Forest. The map captures a mix of recreational and remote transport infrastructure, from the Castle Lakes Airport near Castle Lakes to the rugged routes of Co RD 30 and 149. Distinctive peaks and mesas such as Red Mtn, Seventyone Mtn, and Jarosa Mesa provide sharp vertical relief against the creek-carved basins of Wager Gulch and Cascade Gulch.
