Logging is shut down for the year. Therefore the only plowing is done for access to the powerhouse and the run of river structure on the Ashlu. I have not been up there lately, but from what I hear and looking on hwy webcams. The road is snowed in from the upstream of the powerhouse. Travel up there is not recommended without snow tires, 4x4 and good road clearance. The road can get heavily rutted due to the depth of snow, so cars or low clearance vehicles should not try to go up there. I would also recommend a snow shovel and survival equipment. Please notify people of your schedule and where abouts too, because if your get in trouble up there you are pretty much on your own (no cell service).
