Ibex Mountain is a cinder cone in the Yukon Territory, Canada, located 33 km southwest of Whitehorse and 12 km southeast of Mount Arkell. It is in a group of basaltic cones and lava flows called Alligator Lake volcanic complex and is in the Northern Cordilleran Volcanic Province. It is believed Ibex Mountain last erupted during the Pleistocene.[1] Ibex Mountain is at the head of the Ibex River, which is southeast of Whitehorse. There is a road that runs close to Ibex Lake on the southeast side of the summit. From there is the hike to the summit of the cone.[2]

Basalt at Ibex Mountain has been dated to 2.4 million years old via Potassium-argon dating. The cone survived the ice age because of the elevation above most of the ice (above 1,800 m or 5,900 ft).[3]

The Ibex Valley, located approximately 16 kilometres (9.9 mi) west of Whitehorse, is named after the cone.
