Moolock Mountain is a 4,965-foot summit on the western edge of Washington’s Cascade Range in the Mount Baker-Snoqualmie National Forest. Though modest by Cascade standards, it is notable for its steep, prominent rise above nearby terrain. The peak lies just southeast of Lake Moolock, while its unofficial name preserves the Chinook Jargon word for “elk,” reflecting a trade language once widely used across the Pacific Northwest. Its slopes drain into tributaries of the North and Middle Forks of the Snoqualmie River. The mountain stands in a marine west coast climate shaped by Pacific storms, and its landscape was formed by uplift, faulting, and repeated glaciation.
