The Willow Creek landslide: a large valley-blocking slide in Wyoming<\/h5>\n

The Jackson Hole News and Guide is carrying a report<\/a> about the Willow Creek landslide, a new, large, valley-blocking slide in the Wyoming Range in the USA.\u00a0 The slide, located in\u00a0 Lincoln County, appears to be substantial:<\/p>\n

The report gives some details about the landslide<\/a>, and its discovery:<\/p>\n

\n

To [Dustin Child’s] eye the landslide was as high as 200 feet in places, covered 1\/4 mile of the Willow Creek canyon and formed a 15- to 20-acre lake that\u2019s probably 30 or 40 feet deep. As for the hazard, he didn\u2019t think there was one.<\/p><\/blockquote>\n<\/div>\n

\u201cIt could possibly could do something next spring, but there\u2019s so much debris,\u201d Child said. \u201cIt\u2019s an unreal amount of debris. It dammed it up as far as it\u2019s going to go, and now the river\u2019s cut a stream between the debris pile and the far west side.\u201d<\/p>\n<\/div>\n

\n

It\u2019s unclear when the yet-to-be named landslide was triggered, or if it all came down at once or slowly over the course of the spring. The remote geological phenomenon was discovered this past week, when a Bridger-Teton National Forest firefighter saw that a mountainside had given way from above.<\/p>\n<\/div>\n<\/blockquote>\n

\n

\u201cThey were doing a flight, looking for a fire,\u201d Bridger-Teton spokeswoman Mary Cernicek said. \u201cThey didn\u2019t find the fire, but they found the landslide.\u201d<\/p><\/blockquote>\n<\/div>\n

The slide appears to be a mobile earth \/ mud flow, which has entrained a significant amount of debris from within the channel.\u00a0 Note the deep erosion and sidewall cutting in the upper reaches of the landslide (before the major bend in the landslide track), and then the apparent deposition, starting a short distance downslope from this point.<\/p>\n

This is of course not an unusual event for Wyoming.\u00a0 Previous examples include the spectacular Bighorn Mountains landslide<\/a> in 2015 and the Snake River landslide<\/a> in 2011 (including the brilliant video).<\/p>\n","protected":false},"excerpt":{"rendered":"
