- <p>Still experiencing large rolling thunder collapses. Some were even in old skin track. Poor structure remains. Dug a pit in a very similar location to 12/24, 9,700 E below High Ivory, HS 85-100cm, CTM11 SC down 45 cm on the 20201211 FCsf layer that has seen all the action, ECTP 14 same layer. ECTN11 down 20cm on FC above the PPrm that was buried 20201222, hopefully not a problem going forward, but I will continue tracking for the meantime. Results from almost same location on 12/24 HS 78cm, ECTP18 down 40cm, FCsf.</p>
No new wind slab observed today, traveled in mostly protected areas though.
1st & 2nd Picture of ECT/pit, upper line is the PPrm down ~20cm, second line/fracture is the failure down 45cm on the 20201211 FCsf.
3rd picture the PPrm buried ~20cm down.
I do think the considerable rating is still warranted due to the widespread/stubborn nature=possible and potential of up to size 3. Lack of natural activity and max size possible being size 2 would start to suggest moderate. After seeing the Days Fork activity and the booming collapses/connectivity of the slab I think size 3 are possible.

- <p>Problem persists. I have not been able to rule out the W, SW, SE aspects yet.</p>
Up to about 3-4" of new light density snow observed today, really helped the low angle skiing. Noted a little graupel mixed in to new snow, but not consistent amount. Good supportable powder skiing to be had.
