Turtle Mountain is an anticline of Paleozoic Rundle Group carbonates thrust over weaker Mesozoic clastics and coals. Summit fissures at the apex of the anticline likely allowed water to infiltrate and weaken the slightly-soluble carbonates within the mountain face, while the supporting underlying clastics were undermined by valley glaciation followed by erosion from the Crowsnest River.
The 1903 landslide removed the top of Turtle Mountain, leaving a present elevation of 2,109 metres (6,920 feet) for the north peak and 2,200 metres (7,217 feet) for the south peak.
