Wider weather episode

The melting of record snowpack combined with heavy rain to saturate soils in the western Bighorn Mountains. Land below a section of U.S. Highway 14 above Shell Falls gave way near milepost 31.5 making travel on the highway unsafe. The slide, which measured at least 100 feet long, closed the highway for about three weeks.
