Intermittent movement of the Red Creek Landslide has caused settling and cracking of U.S. Highway 50 west of Gunnison, Colorado, for more than 30 years. Significant degradation of the roadway has resulted in extensive repair costs and traffic delays. Geomorphic and computer stability analyses support the theory that the active Red Creek Landslide is the partial reactivation of a larger, ancient paleolandslide, with a basal rupture surface located predominantly in the Morrison Formation. The original paleolandslide may have been triggered by an earthquake coupled with a high water table. Creation of the Blue Mesa Reservoir submerged approximately 50 percent of the paleolandslide. Some clay layers within the Morrison...

On 26 October 2011, engineers blew a hole in the base of Washington state's Condit Dam, loosing nearly a million cubic meters of water in an instant. The surge of water, sand, and mud marked the end of the 38-meter-tall concrete dam that had blocked the White Salmon River for nearly 100 years and the beginning of a rapid transformation of the downstream environment. Using river gauge measurements, time-lapse photography, and other techniques, Wilcox et al. tracked how the White Salmon River evolved in the wake of the breach.
