Thunder Falls

Thunder Falls is best seen where the Yellowhead Highway crosses over the railroad tracks along Moose Lake in Mount Robson Provincial Park, approximately 11km east of Red Pass.Mount Robson Provincial Park has some pretty big waterfalls, but most of them are deep in the backcountry. Thunder Falls, while not traditionally accessible, is quite visible from across Moose Lake and may be one of the biggest front country waterfalls in the Rockies. This is rather surprising considering the stream along which this waterfall occurs doesn't appear to have a name.
The falls begin with a veiling plunge of about 140 feet, then cascade down a steep slope of boulders piled on top of the bedrock before hitting a small pool then cascading over a second cliff band for about 175 feet. The entire drop registers about 375 feet tall, with a much longer runout over more talus below the falls. During the summer the stream harboring the falls moves a substantial volume of water thanks to its large drainage area, so even from across Moose Lake the falls appear quite significant.Thunder Falls is the officially registered name of this waterfall. In the past seen the falls referred to as both Rainbow Falls and Rockingham Falls, but the sources of these names seems to have disappeared, so the validity of this history is certainly in question.
