"Large crown in lower meadows west side of beehive basin above jack creek. Both meadows in lower fight of photo went. Southwest aspect. Far right meadow crown is visible and entire face went. Left meadow is hard to see but 1/3 of face slid. I would guess 3-6 foot crown from how visible it was from moonlight." Photo: Chad Wilkinson

    • On 2/9/20 we saw deep avalanche crowns throughout the Bridger Range. These broke at various times throughout the recent storm that deposited 4 feet of snow with over 4" of SWE in the last week. This photo shows crowns from avalanches that broke across the entire drainage of Truman Gulch. Photo: GNFAC

    We saw a group of six snowmobilers who said they triggered these slides in McAtee Basin on the left side of the meadow on Saturday, Feb 8. I didn't see tracks up on the hill or sidehill tracks so they may have triggered the slope from the flats below. The debris runs all the way to bottom of the hill. Photo: K Peaslee
