Black Canyon of the Gunnison

We're on our way to Lake City, Colorado to climb some 14ers. Along the way, we checked out another national park -- Black Canyon of the Gunnison, east of Montrose Colorado. Pretty spectacular canyon, we spent about 3 hours walking to all of the viewpoints from the scenic rim drive. Access to the bottom of the canyon is very difficult (very steep) with "unavoidable poison ivy". Oh boy. We skipped that part. Maybe another time. But the fishing is supposed to be superb, with an amazing salmonfly hatch...
