An off rode side trip while on the way to The National Sand Dunes State Park provided me with a panoramic view of storm clouds gathering on the 13,000 ft peaks of the Sangre de Cristo Mountain Range. The Sangre de Cristo Mountains are the southernmost subrange of the Rocky Mountains. They are located in Southern Colorado and Northern New Mexico. The mountains run from Poncha Pass in South-Central Colorado, trending southeast and south, ending at Glorieta Pass, southeast of Santa Fe, New Mexico.
Clouds present a dramatic back drop while driving HWY 150 toward The Great Sand Dunes National Park. Particles of sand originate in the Sangre de Cristo Mountains, and the San Juan Mountains to the west.
The Great Sand Dunes are located on the eastern side of the remote, high-mountain San Luis Valley, between the Blanca Massif and Crestone Needle, they are the tallest sand dunes in North America. The dunes cover approximately 39 square miles and rise to almost 750' above the valley floor.
