I just came from there last weekend and you got a total of 16 miles of dirt road driving even though there is a short paved section before Patriarch Grove turnoff then turns dirt again and makes a steep and very washboarded climb, but the whole dirt road is that way. There is no snow on the road just a few patches off to the side as you get to the TH. I went very slow and it took me an hour and a half to get to the TH and I have a high clearance 2wd ford ranger so if your in a low clearance car it will take at least that long once you hit dirt which is right after you pass the Schulman Grove turnoff.
