Fifth of July Mountain is a 7,696-foot summit in the Entiat Mountains of Washington’s North Cascades, within the Glacier Peak Wilderness and Okanogan–Wenatchee National Forest. Surveyor Albert Hale Sylvester named it for the date of his visit, giving the peak an unusually straightforward name origin. Its runoff flows west into Rock Creek and the Chiwawa River and east into Cow Creek, a tributary of the Entiat River. The mountain stands in a landscape shaped by uplift, faulting, and repeated glaciation. East of the Cascade crest, it is somewhat drier than the western side, but the region still receives heavy winter snow, with lingering spring snow and occasional summer thunderstorms.
