It is also a Colorado Natural Area and an Area of Critical Environmental Concern.[1][2][1] The earthflow, a slow moving landslide, crawled down the valley about 700 years ago creating the {{convert|4|mi|km}} long and {{convert|2000|ft|m}} wide mass.[1][2] The earthflow lies a few miles south east of Lake City.[2] The landmark site covers {{convert|1291|acre|ha}} and is owned by the US Forest Service and the Bureau of Land Management. It is "a striking example of mass wasting (the movement of large masses of earth material)." Lake San Cristobal was dammed by the earthflow.[3] A second earthflow has been moving continuously for about 300 years over older stable rock.[1] It moves at a rate of about 7 meters (23 feet) per year.[4] The area is a habitat for elk and deer.[2] It is crossed by Colorado Highway 149, the principal highway of the area connecting Lake City, Colorado with Creede.
