Went up Tinkham to the pit, beyond there ruts were only in for another few hundred feet. It was absolutely impossible to break trail. I had no expectations for the day, snowpack was deep bottomless unconsolidated water-saturated slush with a few inches of fresh snow on top. Always a good day when it's snowing though.
Tinkham is now blocked by 4 berms, one small one at the exit and a series of three at the road entrance. There is a slightly off-camber bypass that's not too bad. I imagine DOT will take care of blocking the bypass after the next storm.
