Traveling to Crater Lake,OR? -

I m planning for a travel to Crater Lake,OR for Thanksgiving. The whether says there might be a snow on friday or saturday. Is Chains mandatory en route to Crater Lake? How bad the snow in Crater Lake is? Do they clean the snow on roads?

If coming from central Oregon, chains could be required en route. Note that the north entrance to the park is closed, as well as Rim Drive. Today (Friday, November 20th) there are 17 inches of snow on the ground at Crater Lake Village.If arriving from the west side, then chains probably won t be needed until approximately the 3000 to 3500 foot elevation. That makes the last 20 miles of road subject to snow and chains. Even if chains aren t needed on the tires, carrying them would still be required.Snow plows do not clean the road. They remove most of the snow covering. If more snow is expected��or extended solid freezing weather��they scrape the surface down to an inch or two deep, leaving an excellent surface for snow tires, chains, and studded tires. If melting or rain is expected, they try and remove most of the snow covering but not close to the point of nicking the road or damaging the markers.
