Notes

Snowmobilers near lionhead witnessed three avalanches on Jan 7, 2019. One natural and two remotely triggered.

From email: "We had been climbing a safe slope adjacent to this slide... 24 inch crown and about 200 feet wide... Occurred at 1:38PM on an easterly wind loaded slope...The third slide... was triggered when the group passed below a short steep slope. We were well spaced and using safe practices when the number 6 sled in line remote triggered the avalanche. It flowed across our tracks and was about 12 inches deep. No one was caught or threatened.... on a southeast aspect."
