Snow starts around 34km mark. Just had enough clearance in a stock Tacoma with skid plates, any lower and you'll be high centred on the snow between the tire ruts. No one has broken tracks past 53km. There's a couple smooth sections but I imagine the road might get pretty rough after the snow melts. Overall not horrible currently if you take it slow in the snow and use good line choice!
Thanks for the super detailed report Theo! I'm surprised it was snow free so far down. Great news for anyone trying to access the upper reaches of the valley
