The Spanish Peaks are a pair of prominent mountains located in southwestern Huerfano County, Colorado.
The Spanish Peaks are situated 100 miles (160 km) due south of Colorado Springs.
The Spanish Peaks were formed by two separate shallow (or hypabyssal) igneous intrusions during the Late-Oligocene epoch of the Paleogene Period.
[4][5] The Spanish Peaks were designated a National Natural Landmark in 1976 as two of the best known examples of igneous dikes.
A classic book about travel to the region in the 1840s is Wah-to-yah and the Taos Trail, by Lewis Garrard.
