Tim Palmer is the kind of guest we welcome back often to the Exchange.
Because he provides such a wealth of information in so many realms.
It comes down to this: if it involves water in our region--flowing or frozen--Tim probably knows about it.
He's written field guides to rivers in both states, a book about glaciers in California, and more. He and his wife recently floated the Rogue River, all the way from Lost Creek Dam to the Pacific... journey not possible (because of dams) just a few years ago.
