Slee,

The Weyerhauser Vail Tree Farm map will be of help. You can get one at Metzger Maps, right off the freeway in S> Tacoma on T. Mall BLVD. around 64th street. They have all kinds of WA state maps too. The Weyerhaueser maps ONLY show roads though- will not help if you want topo.

You may want to check out those GMU maps mentioned earlier. They are topo, and show GMU boundaries very well, but are not nearly as large a scale as USGS topos.
Place is L C Sportsmaps, 20606 SE 24oth St, Maple Valley, WA, 98038; 425-432-5508.

FYI: it is often hard to get a truly up to date topo of industrial timberland because of the constant road building and cutting/regrowth process.

That area is not real hard to figure out with a WEYCO map and a couple scouting trips.
