Level Mountain
Level Mountain is a massive shield volcano in Cassiar Country, northwestern British Columbia, Canada, located just southeast of Callison Ranch, southwest of Dease Lake and about 50 km (31 mi) north of Mount Edziza. It lies on the Nahlin Plateau, comprising a series of buttes and ridges. The shield is lightly glaciated, as compared to the Coast Mountains just to the west. The only named summit of Level Mountain is Meszah Peak on the north side of the shield with an elevation of 2,190 m (7,185 ft), making it the highest point of Level Mountain. Immediately to the west, however, are the Heart Peaks, a related volcanic range just east of the Sheslay River, which is the edge of the Nahlin Plateau.Level Mountain rises above adjacent forested lowlands and undulating alpine areas surround the steeper central peaks. Streams that originate from these peaks drain across the Nahlin Plateau.
