There are four prominent waterfalls in the basin of a short tributary of Sulphide Creek, on the southeast flank of 9,127-foot (2,781m) Mount Shuksan in North Cascades National Park, Washington. Seahpo Peak Falls and Cloudcap Falls, the taller two of the three, are located on separate streams that converge and plunge over Rockflow Canyon Falls. The unnamed outlet stream from these waterfalls flows into Sulphide Creek, which flows into the Baker River. Another waterfall is Jagged Ridge Falls, on a tributary of the unnamed stream.

Seahpo Peak Falls, at 48.8136°N -121.5506°W, is an intermittent waterfall on an unnamed glacial stream coming off Seahpo Peak. The largest (but not tallest) of the waterfalls on Mount Shuksan, it stands about 2,200 feet (670m) high and has 6 distinct tiers, the largest of which drops about 500 sheer feet (152m) .[1]
It is located near the five waterfalls of Sulphide Basin.[2]
