If they open the gates, you can access through end of Rose Valley Rd to the 1600 line, at the Headquarters Camp off Headquarters Rd, the 1600 line again, just other end, and the 4700 bridge gate off the 4100 rd in Toutle, and possibily the end of Sightly/Canal Rd in Toutle, to the 1300 rd area I believe. Good luck!
