Plowing began today on the west side of the Going-to-the-Sun Road. Crews should have a swath cut to Avalanche by the weekend, but don't expect to ride your bike on the road — below the snow is a thick layer of ice, that will take a few days to melt off, it it ever warms up. Last night the Park saw about four inches of new snow and a rain-snow mix is in the forecast for the next few days. On the east side, Park plow crews are also working on plowing the Two Medicine Road and they're encountering some very large drifts.
