Iceland has much volcanism right up to the surface. Some mighty deep holes would be needed on the CO Rockies for that. Might try Yellowstone, though.

Here in Colorado, we have a number of “hot springs” (Manitou, Pegosa, etc) that are 100 deg F or hotter. Here is a map from the Colorado Geothermal Survey that shows several of these active areas.
