The RTMM Docks will have all of the Tongass Ones ... I think ALL of them are SPB's. Some were only a dock, single pier, others just a starting point. I put in piers, boats, landscaping, wsindsocks, fuel, etc. So each one now is a "fun" place to visit. If you go to the FAQ in the Airport Facilities, Table II has all of the Tongass X SPBs. (I don't know much about Google Earth).
