General Observations

Myself and a large group (15) rode snowmobiles from the Richardson Monument to the bottom of the glacial cirque directly East of College glacier, “No Name” glacier some call it.  On the way up the valley where the Arctic Man race finish line used to be, we noticed lots of shooting cracks and settling snow on either side of the valley,  As we rode over the top of the plateau nicknamed “First Aid,” by the Arctic Man Race I noticed a quite a few small slides and a couple of large ones in the valley that Gunn Creek originates from, due West, or on the back side of the mountain nicknamed “Courage.”  We noticed a number of other slides throughout our days ride, not confined to any one aspect or slope.  On the way back to the truck, I stopped at First Aid again and throughout the day, quite a few more of the slopes at the head of Gunn Creek had slid.  It was noticeably warm in direct sunlight, and the snowpack where the slides occurred was somewhat shallow, between 1-3 ft.  In my opinion, the recent snow that Isabel Pass has received is extremely touchy and will settle or slide if it is on a steep enough slope.  Avoid traveling on steep slopes or through terrain traps with large slopes above them.
