The Roost is a 6,705 ft summit in the Picket Range which is a sub-range of the North Cascades Range of Washington state, United States. It is located within North Cascades National Park and Stephen Mather Wilderness, and is situated one mile north of Mount Ross. Like many North Cascades peaks, The Roost is more notable for its large, steep rise above local terrain than for its absolute elevation. The Roost was first climbed on July 12, 1966 by John and Taffy Roper. The nearest higher peak is Glee Peak, to the north-northwest. Precipitation runoff from the mountain drains into the Skagit River.
