More detailed information about the avalanche: 

We observed this crown from a distance of about 1.5 miles. Crown hieght and width were estimated.  No known or visible trigger,  ie: old tracks were visible in the bowl.  It did fail to the rocks/ground.  Similar pit data showed a buried surface hoar layer at 160cm and very loose depth hoar near the ground.  The crust and facet problem was also preserved above the depth hoar.  Rapid loading and variable snow depths are suspected culprit as we recieved 100cm of  new snow in the previous week.
