Very strong winds - Back side of Sherwins

Aimed to get deeper into the lakes Basin than I did today.  Thankful for the trench to follow from the end of Old Mammoth Rd to Panorma Dome, then progress slowed with breaking trail from there to Lake Mary Rd. with boot top ski penetration.  There was about 1 meter of new snow in more sheltered areas at 8700', with a total snow depth of 2-2.2meters.  Was dissapointed to find that the Tamarack x-country ski trails had no signs of being groomed, with deep wind drifts. (see attached videos).  So went up the southwesterly facing wind-stripped slopes on the backside of the Sherwins a ways to 9200' where breaking trail was relatively easy.  Poked over the ridge a few times on to the upper northwest facing slopes where snow was being deposited, but didn't want to get sucked down too far where the real deposition was happening and concern was greater.  Didn't experience any shooting cracks or slope failures on my route, but again I was staying away from areas of greater concern.  Southerly cross-slope winds were quite strong (see attached videos).
