Drove up Friday morning. The last mile to the trailhead is covered in snow, ice and mud. Most of this portion doesn‘t get any sunlight this time of year so it doesn‘t melt. The up hill sections are especially bad. I have a 3/4 Ton GMC with mud tires and a Winch so I was fine. I wouldn‘t advise trying in anything less than a truck or a Jeep with good tires. Good chance you could just slide into a ditch or a tree. On the way down I slid in a couple spots so be careful.
Sidenote. Good amount of snow on trail to Capitol. Didn‘t feel like post holing the whole way up. I could see a good amount of snow collecting on the the North side of Capitol.
The picture of Capitol is from the trailhead. The other picture is a Good section of the road down.
