Its nearest higher peak is Elliott Peak, 1.6 km (0.99 mi) to the southeast.[1] Both can be seen from the David Thompson Highway and Abraham Lake. Precipitation runoff from Sentinel Mountain drains into tributaries of the North Saskatchewan River. The mountain was named in 1893 by Arthur P. Coleman and was officially adopted in 1928 by the Geographical Names Board of Canada.[2]
