Used as a landmark by Native-Americans, the first recorded mention of "Chimney Rock" was in 1827 by Joshua Pilcher. Pilcher had journeyed up the Platte River valley to the Salt Lake rendezvous of the Rocky Mountain fur trappers.
Based on sketches, paintings, written accounts, and a 1897 photograph, Chimney Rock was taller when it was first seen by settlers, but has been reduced in height since then by erosion and lightning.

The pillar consists primarily of Brule clay interlayered with volcanic ash and Arikaree sandstone. The harder sandstone layers near the top have protected the pillar since it broke away from the retreating cliff line to the south.
