Toured up to Red Cone, traversed across to Hollywood Bowl, down to McCloud Lake, and back to Tamarack to look at the timing of solar warming across E-S-W-N aspects and by elevation. Very nice day with very little wind and warm temps (though not as warm up higher as it has been).
-E aspects were supportable spring corn up to about 10,000' by 1030am. By 1130am E aspects were just starting to turn to unsupported.
-N aspects below 9200' had also softened to moist polycrystals by 11am but were still crusty above 9700' at 1230pm.
-W aspects were crusty above 9200' until after we were down by 1pm.
-Almost all surfaces were spring melt-freeze with consistent density (extrapolated from probing) down to a very hard crust layer that was down between 60 and 100cm.
-Above 10,300' N aspects were cold wintry snow with many previous wind deposits. Very hard jumping on some of there caused some cracking right at their edges but that's it. They broke were they were about 4" thick on a layer of small faceted grains.
-At the top of Red Cone at 1215pm: Sky=Few clouds, Wind=Light from the W gusting to moderate, Surface=moist polycrystals, Ski pen=1cm, Boot pen=5cm, Tair=5 deg C, Tsurf and T-20=0 deg C.
Only small rollers and sluffs from our skis, even where E facing slopes had boot top penetration after noon. No new natural rollers or point releases today.
