Sheep Mountain is a 6,166-foot-elevation (1,879-meter) summit near the western edge of the North Cascades, in Snohomish County of Washington state. It is located one mile east of Barlow Pass along the Mountain Loop Highway near the Monte Cristo area. It is situated on land administered by the Mount Baker-Snoqualmie National Forest. Back in the old mining days of the late 1800s, the long sub-range stretching from Cadet Peak to Sheep Mountain was known as Pride of the Mountains Range. Precipitation runoff from the mountain drains into tributaries of the Sauk River.
