Dawson Falls is a mini-Niagara about 60 feet high on the Murtle River in Wells Gray Provincial Park, British Columbia. There are no fewer than 4 major cataracts on this river including Helmcken Falls ( www.pbase.com/darby2/image/118312026/original  )about 4km downstream from this point where the river plunges over a 475 foot precipice into a volcanic gorge. I did a Gigapan of it as well. The river continues into the Clearwater River and eventually merges with the North Thompson and finally the Fraser which empties into the Pacific Ocean at Vancouver.
Wells Gray Park has more than 20 major waterfalls.

Best times to see the falls are in early spring when there's lots of water or mid winter when there's lots of ice. The area upstream receives a lot of snow during winter so there's no shortage of water.

Regarding exposures, I did two passes, one at 1/60 second and this one at 1/40 sec. just to give some blur to the movement of the water.
