Finally cleared the last of the snow at the 8,500 foot level today. I'm planning to head up next week. Prior to today, you could enter the north or south ends, and travel a few miles, but you'd have to exit the same way you came in. Now you can travel the full 30 miles on Highway 89 through the park.
UPDATE: SR 89 through @
LassenNPS is now OPEN to through traffic!
