I would like to find a good detailed map for the Olympic Peninsula, particularly the Forks area rivers. Does anybody have any suggestions. I already have a Metsker map but it doesn't get into enough detail. I looked at some of those Green Trail maps but the area I was interested in was on the edge. They also had some Forest Service maps but not the Forks area. Are those 3' x 5'stream maps of Washington (advertised in the Seattle PI Sports)any good?
