Remotely triggered slide just off of and South of Twin Lakes Pass. SS-ASr-R3-D1.5 This bed surface had slid back in January and the snow since Thursday (now totaling 20 cm or 8") was sitting on top of very weak faceted snow. The near-surface facets that have been preserved underneath the Thursday snow really just needed a large enough slab to make them reactive. All my stability tests today indicated they required a fairly steep slope (approaching 40 degrees) to make them reactive.
