Colorado's Hot Spots

Developing research uncovering new potential for Colorado's geothermal resources.

The Interpretive Geothermal Heat Flow Map of Colorado depicts the movement of heat from the Earth's interior to its surface in Colorado. The geographic distribution of heat flow is one of several indicators of the location of potential geothermal resources in Colorado.

Mapping Colorado's Geology

Through our ongoing STATEMAP geologic mapping program

Our STATEMAP mapping program has produced 103 geologic quadrangles to date, with another 9 in progress. The maps are focused on high-growth areas throughout Colorado. STATEMAP is one of three components of the National Cooperative Geologic Mapping Program (NCGMP).
