Road is in great condition right up to the gate (marked in Gaia on Otter Creek Road). Driving on the lava rock is so cool. Ruby Creek continues down into the valley below, and looks in decent condition as well. We just drove up to the area to check out the volcano cone. There's no real trailhead, but we climbed a hill for some views of the valley. Highly recommend checking out Atlin, Kershaw's Coffee, and the volcano field and surrounding roads.

We didn't take the marked road up to the Boulder Dam, just past the Surprise Lake Rec Site. It looked like it was in decent shape, but I can't report on how much the "high clearance 4x4" recommendation is true.
