Update: Forest Roads 99 and 26 are also now open, just in time for the 35th anniversary celebration of the Mt St Helens eruption.
As of Weds, May 6th, Forest Road 25 between Randall and Forest Road 90 is now open. The route provides a connection along the east (crater) side of Mt St Helens during the summer months. This is one of the earliest openings in many years. See this earlier post for more information.
