Seven Fingered Jack is a mountain in theNorth Cascades in theU.S. state ofWashington. It is located at the north end of theEntiat Mountains, a sub-range of theCascade Range. It is part of a three-peak group called the Entiat Cirque which includesMount Maude andMount Fernow. Seven Fingered Jack is about 4 miles (6.4 km) south ofHolden.[2] The peak is in theGlacier Peak Wilderness ofWenatchee National Forest.
Sources differ over the height of Seven Fingered Jack. Peakbagger.com says it is 9,100 feet (2,800 m),[1] peakware.com says 9,077 feet (2,767 m),[3] and theUnited States Geological Survey cites 9,022 feet (2,750 m) in itsGeographic Names Information System database.[2] Its rank also differs by source. Seven Fingered Jack is the twelfth-highest peak in Washington, according to peakbagger.com[4] and fourteenth-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 beingMount Maude and Mount Fernow. All three are over 9,000 feet (2,700 m).[5] Together they form a high, curved ridge from which the headwaters of theEntiat River flow eastward. There are a number ofglaciers 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 theChiwawa River, which flows south to theWenatchee River. Thus Seven Fingered Jack sits on the boundary between thedrainage basins of the Entiat and Wenatchee rivers. Both rivers are tributaries of theColumbia River.[6]
Seven Fingered Jack was once called the Entiat Needles, after their distinctive craggy granite summits. It was given its present name byAlbert H. Sylvester,[3] who served as aUSGS topographer and then, from 1908 to 1931, with theForest Service as the Forest Supervisor of theWenatchee National Forest. Over the course of his career he gave over 3,000 names in the region.[7]
