Jackass Mountain is a mountain in the North Cascades of the Cascade Range in southwestern British Columbia, Canada, located 18 km (11 mi) southeast of Lytton and 9 km (6 mi) south of Mount Lytton. It is named for the muletrains that ventured north to the Cariboo gold fields; apparently some did not make it over the bluff and perished in a fall, hence the name.[3]
