Welcome to Glenrock! Named for the large rock in the glen just west of the community’s current location, Glenrock got its beginnings as a rest stop and crossroads of the major westward trails. The Oregon, Bozeman, Texas, California and Mormon trails all came together along Deer Creek and the Platte River. Soon it became the site of the Deer Creek Station and Stage Stop. Coal was discovered in the area and Glenrock soon became a mining town. Soon the mines played out by oil were found in the area. Once again, the boom was on. Be sure to stop by the Deer Creek Museum and the Glenrock Paleontological Museum to see historic artifacts from the surrounding area. Home to 2,231 people. Elevation 5,009 ft.
