The Slumgullion Earthflow in the San Juan Mountains in Hinsdale County, Colorado has been a National Natural Landmark since 1983. It is also a Colorado Natural Area and an Area of Critical Environmental Concern.〔〔 The earthflow, a slow moving landslide, crawled down the valley about 700 years ago creating the long and wide mass.〔〔 The earthflow lies a few miles south east of Lake City.〔(【引用サイトリンク】 title=Slumgullion Earthflow )〕 The landmark site covers 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.〔(【引用サイトリンク】 title=Slumgullion Earthflow )〕 The earthflow has been moving continuously for about 300 years over older stable rock.〔 It moves at a rate of about 7 meters (23 feet) per year. The area is a habitat for elk and deer.〔 == References ==
