Over the Snowpack Crest

We suggested a few days ago that the end of the snow accumulation season was nigh.  Observations from the Snowbird SNOTEL show that peak snowpack water equivalent was reached on April 28 (32.7") and that we dropped below 30" yesterday.

The Alta-Collins snow depth fluctuated around 100 inches for the better part of a month, but is now in decline, having dropped to around 90 inches this morning.

Forecasts through the end of the work week keep us generally dry.  We're likely over the crest now even on high north facing terrain.  

We got out for some "snirty dancing" on Saturday.  At the start of our tour, it was 47˚F at 7 am.  Disgusting.  Nevertheless, there was a shallow freeze and turns were good on southern aspects where the most recent storm snow had melted out.  Look close and you can see the snirt – dirty snow where dust from storms over the past few weeks has emerged onto the snow surface.  


North aspects were already soft by about 10 am and still had some of that storm snow remaining, which was sticky and grippy.  I suspect this snow will be melted off soon if it hasn't already, leaving snirt on all aspects.
