General Comments

I noticed some significant slides in Straight canyon (Big Kahuna) and off the East Slope of Mendon Peak (Bird Canyon).  It looked like someone was kicking off slides all the way up the ridge headed to Big Kahuna but I couldn't see any skin tracks.  There were probably a half a dozen slides but the most significant started at 8000 ft and ran to 6600 ft.  The deposit looked pretty significant in the bottom gully.  I would estimate the soft slab up top to be approximately 50 feet wide and not too deep, probably just the most recent layer of snow.  There were some other decent sized slides into Bird canyon.  Like I said earlier, it looked like someone was kicking the slides off because there were so many but I couldn't see any tracks with a 60X spotting scope.  The slides looked pretty recent like today or maybe yesterday.  I am guessing the wind loading from last night overloaded the latest weak layer.  The were two other small slides in Deep canyon but they did not run far at all. 

I took the photos on 3-1-10 (Toby Weed)
