Summer Coon
An American volcano in Colorado
Summer Coon is an Oligocene stratovolcano[1] in Saguache County, Colorado that erupted between 24 and 34 million years ago. It is located 6 miles (9.6 km) north of Del Norte, Colorado and is on the western edge of the San Luis Valley. It is in the Rio Grande National Forest.[2]
The New Mexico Geological Society published an article on it in 1971. Various studies of the area and its volcanic intrusions have been carried out.[3] These include a study of trace element variations at the summit.[4] La Ventana Arch resulted from erosion following volcanic activity.[5]
