Ruby Mountain

Ruby Mountain, locally known as Old Volcano, is a cinder cone in Stikine Region, British Columbia, Canada, located 23 km (14 mi) northeast of Atlin and 6 km (4 mi) south of Mount Barham. A recent collapse on the volcano's eastern side created a large landslide which dissects this side of Ruby Mountain. The volcano is the largest feature within the Atlin Volcanic Field.

Ruby Mountain, locally known as Old Volcano, is a cinder cone in Stikine Region, British Columbia, Canada, located 23 km (14 mi) northeast of Atlin and 6 km (4 mi) south of Mount Barham. A recent collapse on the volcano's eastern side created a large landslide which dissects this side of Ruby Mountain. The volcano is the largest feature within the Atlin Volcanic Field.

November 8, 1898 eruption

Reports were received of eruptions in the Ruby Mountain area, about 80 km (50 mi) south of Gladys Lake, near the end of the 19th century. Miners working in the area were said to be able to work during the dark nights under the glow of the eruption. However, there has been no evidence found, such as lava flows young enough to have been the site of a historical eruption.
