The road through Lassen Park is still not open all the way through. Snow removal there is always a daunting task. This year it has been compounded not only by the heavy snowfall, but buried beneath the snow are fallen trees and rocks in the road. The last time the park road opened in July was in 2011 on the 16. And for a little bit of trivia, while the road is part of Highway 89, it is known inside the park as US 1.
