Two pockets remotely triggered from the ridgeline.

From Canyons snow safety - Skier remotely triggered from ridgetop. Two pockets each about 50' wide. Total snow depth in this area is 130cms. It has slid multiple times this year. The snowpack structure consists of faceted snow from the ground to 70cms up from ground and the top 60cms is snow from the previous few storms with the first one on February 20th. The slide path is called La Frontera and we control this area from time to time to prevent bigger slides from hitting the ski area. We do not control this area after every storm nor do we control this area for skier traffic as it is out of bounds and not part of the ski area.
