Notes

From e-mail on 3/15/20: "At around 1230pm today, everything that was steeper than 35 degrees in star Creek simultaneously slid on east, north, south aspects. Soft slab 6-12" in thickness. Prior to that, it had been snowing S5 for three hours"

Another email 3/15/20: " observed a round of natural s slab avalanches today, that seemed to run at about noon today on the north aspects of Mt. Republic.  One was a couple hundred feet wide, and looked to happen within the new snow (6"? deep crown), but it stepped down to what appeared to be the new/old snow interface in a couple of spots as well.  Significantly wide pro propagation d deep debris piles.  The snow on Town Hill was cracking a lot early in the day around your skis, but seemed to settle relatively quickly,
