1 Feb 98, 9:30 am - 3:00 pm, Snowy Range.  Accompanied a party of 7 others
(including Kevin Chamberlain) on a tour down Silver Run Creek.  Skied from
Green Rock up the south fork of Sally Creek, across Libby Creek to Bear Lake,
then via the Silver Run jeep road to the meadows above Silver Run Lake.
From there, we skied over to the south fork of Silver Run Creek, dropped
into Silver Run Creek, descended to Barber Lake Road, then cut over to
Corner Mountain parking area via Corner Mountain Loop.

Remarks:  This site was anomalous in that it was much shallower than the
surrounding sites.  It also had an unusually thin consolidated layer (less
than 20 cm, more typical of snowpacks analyzed before the mid-January storms)
and a depth-hoar layer that was remarkable for its large, impressively
faceted crystals and absence of recent sintering. Kevin Chamberlain dug
a much deeper snowpit nearby and found at least 80 cm of consolidated
snow covering depth hoar that had started to become more coherent. Kevin's
pit showed characteristics more representative of the skiing conditions that
we encountered and more typical of pits I'd dug during the past two weeks.
Still, the pit reported here indicates that depth hoar still affects the
stability of the overall snowpack and that, in some places, recent snowfalls
have done little to change the severity of the problem.
