Raton Basin

The Raton Basin is an asymmetric structural basin stretching from Huerfano in Las Animas County, Colorado to Colfax County, New Mexico. Rock layers within the basin are more steeply inclined on the west side than the east side. The basin was named after Raton Pass and Raton, New Mexico. The Raton Basin has always been an important source of coal and more recently, coalbed methane. A very well preserved K-T boundary (Cretaceous-Paleogene boundary) can be seen in this area.
