Mount Prophet, Mountain summit in North Cascades National Park, Washington, US

Mount Prophet is a steep, remote mountain in the North Cascades of Washington, rising between the valleys of the two Beaver Creeks and Arctic Creek west of Ross Lake and east of the Picket Range. Its valley-floor relief gives it a prominence of over 4,000 feet (1,220 m), the 18th greatest in the state.

The mountain was named for Tommy Rowland, a prospector who lived by the Skagit River in the late 19th century and was described as "religiously fanatic." The name refers to his character rather than to any religious site on the peak.

The name honours Tommy Rowland, a prospector described as "religiously fanatic" who lived by the Skagit River in the late 19th century. The peak stands between the valleys of the two Beaver Creeks and Arctic Creek, west of Ross Lake and east of the Picket Range.

The nearest approach is the Little Beaver–Big Beaver Loop, about 26.5 miles (42.6 km) of trail that only brings you to the drainages below the peak; the summit itself has no trail. Few people have attempted the climb because the valleys west of Ross Lake are hard to reach.

Mount Prophet rises more than 4,000 feet (1,220 m) above the floors of the valleys that ring it, which makes it the 18th most prominent peak in Washington. The nearest trail, the Little Beaver–Big Beaver Loop, still leaves about 26.5 miles (42.6 km) to cover.
