Abajo Mountains

The mountain range is located within the Manti–La Sal National Forest.

The highest point within the range is Abajo Peak at 11,360 feet (3,463 m).

[1] This mountain range, like both the La Sal Range and Henry Mountains in the same part of the Colorado Plateau, is formed about igneous intrusions that are relatively resistant to erosion.

The predominant igneous rock is porphyritic hornblende diorite.

Ages of intrusion in the Abajo Mountains fall in the interval from 22 to 29 million years.
