Weather, Mudslide

Chaffee County Rock and Mudslides - July 22,2002, Cottonwood Pass Road (County Road 306) and County Road 162 ("The Dip"), Between 6:00 p.m. and 7:00 p.m. on 22 July 2002 (0000-0100 UTC 23 July), a rock / mudslide occurred on the Cottonwood Pass Road (County Road 306) in the valley north of Mt. Princeton (14,197'), west southwest of Buena Vista, Colorado.

County Road 162, in the valley south of Mt. Princeton, also had significant rainfall and experienced rock and mudslides as well. One main reason for these rock and mudslides is the type of soils and rock in this region.

Geology of the Mt. Princeton Area - Some areas around Mt. Princeton are composed of granite and calcite. The granite is a different composition from that of the Pikes Peak massif, being primarily a mix of quartz monzonite (quartz, triclinic feldspars (sodium, potassium, and calcium aluminum silicates), and mica. When the granite contains very little mica, it tends to be very hard, and large rocks, giant boulders, and even solid granite cliffs are the rule. When the granite contains quite a bit of mica, the granite tends to break up quite easily into smaller pieces. The calcite can be a flaky, white rock, which can break apart easily and turn into a fine white powdery soil. This calcite is what gives the lower southeast slopes of Mt. Princeton (in and near the hot springs) their white color. This area is known as the Chalk Cliffs. NOAA NWS Pueblo, CO - Chaffee County Rock and Mudslides Photo Credits - C.
