More detailed information about the avalanche: 

A few small wet slides on the south east/west face of Laurel mountain.  A few new ones had gone naturally from the start of the day until the end on the SW aspects around 10,000 feet.  The one pictured probably went yesterday or the day before.  Still some wintery snow on the N/NE aspects especially in the batch plant bowls.  The snow sofented to good corn conditons around 10:30AM and turned to mank around 1:30/2pm for elevations around 8,000-10,500.  The pinner couloir was quite poor skiing as there was lots of debree and a few runnels throughout the entire couloir along with several rocks to dodge from recent rockfall off of the side walls.  The mendenhall couloir is still skiable from top to bottom but looks like it will melt out within a week or so.
