Was wandering around the Monitors today to get a look at what the new snow was doing. First went to South Monitor and had a look, not much going on except a new snow slide in the middle of the bowl running about two thirds track. Continued over to West Monitor for a look and did a couple low angled south facing runs. Later in the day walked back over to South monitor to take a look with better visability this time. Noticed a set of tracks off the nob between W and S Monitor. The tracks we saw went off the nob SE facing and down toward the steep SE face of South Monitor, making a hard left near aspens to stay off the steeper terrain in the main bowl of South Monitor. This is where they must have remotely triggered a large slide on the SE facing main bowl in South Monitor, 150ft wide 18" deep running to the flats, also pulling more soft slab of the steep SE facing just under the aspens. Just enough vis to see the crown and debris in the bottom, but not enough time for a pic before the vis was gone again. At first it looked like the tracks went staight into the crown but on closer inspection, realized they remoted it from about 20ft away. Lots of wind loading from the W, SW onto the SE slopes.
