Located 10 miles from Box Elder Station and 10 miles from Bridger Station on the west bank of Deer Creek. In Pony Express days, the station was owned and operated by an Indian Trader by the name of Bisonette, who was Station Keeper for a while. (Henderson) "Deer Creek Station was the name applied in the 60's, but as that outpost fell into disuse, a settlement grew up at the mouth of Deer Creek, which was called Mercedes. After the discovery of coal, the place was named Nuttall, from Wm. Nuttall, who found and developed the coal property. In 1887 it took the name of Glenrock (when the buildings were moved to the present location), from the sandstone eminence near the refinery." The name Glenrock means "Rock in the Valley."
