Work on clearing the North Cascades Highway is coming along. Last year, Nate's family and I took a trip over the first weekend they were open. It's pretty impressive to see the swath that they cut through the snow and a really great way to go on a snowshoeing trip.
They clear small parking areas at all the hiking trailheads that intersect with the highway. You pull in, climb up the 15-20 foot wall of snow and start your snowshoeing trip really deep into some of the wildest mountains in the PNW.
