Sentinel Peak (Jefferson County, Washington)

[3] Rising in the center of Olympic National Park, its nearest higher neighbor is Mount Fromme, 1.42 miles (2.29 km) to the northwest.

[5] The two peaks stand as sentinels above the Dosewalips Valley and Hayden Pass, and were possibly named by an early expedition of the Seattle Mountaineers.

[7][8] Weather fronts originating in the Pacific Ocean travel northeast toward the Olympic Mountains.

As fronts approach, they are forced upward by the peaks (orographic lift), causing them to drop their moisture in the form of rain or snow.

[9] The mountains were sculpted during the Pleistocene era by erosion and glaciers advancing and retreating multiple times.
