Flash Flood — Lincoln, Wyoming

2007-09-05 · near Alpine, Lincoln, Wyoming

Wider weather episode

Heavy rainfall in association with a line of thunderstorms produced two mud and rock slides in Snake River Canyon. Rainfall was estimated at 0.75 to 1.00 inches in less than 30 minutes. Both slides occurred between mile markers 118 and 121 on U.S. Highway 89 just east of Alpine. Vehicles were trapped between the slides for about one hour; however, debris was not completely removed from the road surface for nearly four hours. The larger of the two slides was five feet deep with rocks and uprooted trees within the debris flow.
