General Observations

Took a snow machine up red rock canyon road and skied on the Rainbow Glacier.  Approximately 27 F on the glacier.  The snow was a breakable wind slab on top of deep facets. We dug one pit in a wind loaded slope in the process of digging out our snow machine.  No freeze crust, however facets appeared 5-10 inches below the wind slab and continue to the base of the pack (which was 2-4 feet deep depending on location).  We didn’t observe any natural avalanches or other obvious instabilities.  The skiing conditions were horrible.
