(Mark Morical/The Bulletin/TNS) Photo Gallery MADRAS, Ore. To the west, Mount Jefferson and the Three Sisters glowed a bright white against a clear blue sky. Just below us, winding down an otherwise unimpressive hill in the middle of the high desert, were five different trails, all filled with jumps, berms, concrete pavers and wood features. A mountain biker could spend most of a day here, climbing and then riding down a different trail packed with free-ride flavor.
