A large sinkhole opened in January 2005 at the Ironbridge Development and Golf Course, in the Roaring Fork River Valley, approx. 6 mi. (9.7 km) southeast of Glenwood Springs. Two golf carts inside the structure were lost down the throat of the sinkhole. View is to the northwest, towards the confluence of the Roaring Fork and Colorado rivers at Glenwood Springs. The red cliffs in the background are the Maroon Formation. For scale, note person in white hardhat standing in the snow. Photo credit: Jon White for the CGS.
