Seven Fingered Jack is a mountain in the North Cascades in the U.S. state of Washington. It is located at the north end of the Entiat Mountains, a sub-range of the Cascade Range. It is part of a three-peak group called the Entiat Cirque which includes Mount Maude and Mount Fernow. Seven Fingered Jack is about 4 miles (6.4 km) south of Holden.[2] The peak is in the Glacier Peak Wilderness of Wenatchee National Forest.

Sources differ over the height of Seven Fingered Jack. Peakbagger.com says it is 9,100 ft (2,800 m),[1] peakware.com says 9,077 ft (2,767 m),[3] and the USGS cites 9,022 ft (2,750 m) in its GNIS database.[2] Its rank also differs by source. Seven Fingered Jack is the 12th highest peak in Washington according to peakbagger.com[4] and 14th highest according to peakware.com.[3]
Seven Fingered Jack is the second highest and middle of the three peaks of the Entiat Cirque, the other two being Mount Maude and Mount Fernow. All three are over 9,000 feet.[5] Together they form a high curved ridge from which the headwaters of the Entiat River flow eastward. There are a number of glaciers on Seven Fingered Jack and its neighbors, including Entiat Glacier. Streams flowing down the east and south sides of the mountain enter Spider Meadows, through which flows Phelps Creek, a tributary of the Chiwawa River, which flows south to the Wenatchee River. Thus Seven Fingered Jack sits on the boundary between the drainage basins of the Entiat and Wenatchee rivers. Both rivers are tributaries of the Columbia River.[6]
Seven Fingered Jack was once called the Entiat Needles, after their distinctive craggy granite summits. It was given its present name by Albert H. Sylvester,[3] who served as a USGS topographer and then, from 1908–1931, with the Forest Service as the Forest Supervisor of the Wenatchee National Forest. Over the course of his career he gave over 3,000 names in the region.[7]
