 I toured to 10800’ on Mono Jim peak today.  Leaving the car around 945 this morning the temperature was warm, and the sun was shining through the partly cloudy skies.  Making my way up from tobacco flats to the base of Old Mans bowl, surface conditions were a well frozen supportable Melt Freeze crust.  The climb up old man's bowl was relatively easy, ski penetration was about 5 cm and I was able to make it to the top without ski crampons.   Increasing cloud cover and sustained moderate/ strong winds kept the MF crust from softening much, and my first lap down Old Man bowl was a little crunchy.  While a thin zipper crust kept things interesting the skiing was still predictable and enjoyable.  I opted to head back up to the summit of Mono Jim and check out one of the east chutes. After a short scramble over the summit, I was delighted to find the snow on this more ENE aspect to be quite a bit softer.  While there was still a slight zipper crust hear it was much less noticeable. The larger hazard was navigating through refrozen rollerballs.  Descending the moraines it became obvious that the MF crust had still not softened up but the supportable crust was predictable and fast. Below Tobacco flats, the snow had softened up quite a bit into quazi corn snow.  As the winds increased I saw some evidence of snow transport, though it was not substantial.   I suspect as with the addition of new snow this evening that may change. I observed a few old loose wet avalanches coming off the east side of Mono Jim peak though no signs of instability were noted today.
