The "Grand Sentinel" is the largest of several pillars or pinnacles located on the mountain. It is found part way up the slopes leading from Paradise Valley to Sentinel Pass and rises 120 metres from the scree slope. Its longest face is about 300 metres high.

Samuel Allen originally named this peak Sentinel Mountain.

Pinnacle Mountain is well known for its "rotten" rock and three previous attempts had been unsuccessful before Edward Feuz jr. and Rudolph Aemmer led J.W.A. Hickson to its summit in 1909.

Contrary to what it says in the most recent Rockies guide book ("Not recommended, rotten rock") this outing is recommended as an enjoyable, easy day in a spectacular situation on good rock (for the Rockies). The crux climbing is usually avoided by shinning up an old hemp rope - bags of fun. A comfortable day from Moraine Lake. Dougherty, Selected Alpine Climbs page 126
