Widespread SS-N-1 and 2, and LS-N-1 cycle during yesterday mornings high P.I. rates. Picture from UFO Bowl #3 gives general idea of activity in Provo area from 2/12 storm. Didn't see anything that stepped down in to old snow.

Profile from Timp Divide area below UFO Bowl #1 at 8900', NNW aspect. Early Feb. 3mm SH buried in tact here, 23cm deep. This structure likely a player in some of the SS-N activity from 2/12. approx. 10" of new snow with 1" of H2O not enough of a load to cause step downs into the depth hoar

Early Feb. SH, buried, size 3mm.
