With the number of other waterfalls your great book covers, I’m surprised you didn’t mention Big Brother and Little Brother falls on the White Salmon or the “green bridge” access to that area around the 17 mile mark on SR141. There are a number of Web posts about incredible kayaking over those.
Jim, thanks for the comments! To me the Green Trestle is not that interesting, and it gets a lil crowded at times with Kayakers and you are not supposed to walk on it! Big and Lil brother have even more tangled access issues. There are heaps and heaps of “secrets” I leave out on purpose……ha, so you can find ’em yourself!
