Boulder Creek, North

North Boulder Creek is manky and easy to blunder into the Class VI rapids. Dream Canyon has additional challenge during portage due to the proximity to Boulder. This vertical alpine gorge produces good climbing within these canyons above the popular Boulder Falls before its entrance into Middle Boulder Creek. .
