Sulphide Creek Falls is one of the tallest waterfalls in the United States. It is also one of the hardest to see. There is no maintained trail. The fall is glacier-fed and most reliably visible in mid-summer after snowmelt clears the upper basin.

Sulphide Creek Falls is a tall, moderately large volume waterfall within North Cascades National Park in Washington state that is one of the tallest waterfalls in North America. The falls drop from Sulphide Lake on the southeast side of Mount Shuksan down a narrow flume-like canyon to a broad basin below.

A short history

First named in USGS records in the early 20th century after the sulfur springs that feed the creek's headwaters.

The trail

There is no maintained trail. Reaching the falls requires backcountry travel and route-finding.

Why the waterfall is there

The falls drop over Shuksan Greenschist — metamorphic rock formed roughly 130-170 million years ago and uplifted by the same tectonic activity that built the North Cascades. The cascade exists because Sulphide Lake sits at the lip of a hanging valley carved by Pleistocene glaciation.

Is the water flowing right now?

Most waterfall sites don't tell you this. The waterfall itself is almost never gauged, but a USGS streamgage in the same watershed can tell you whether snowmelt has started, peaked, or run dry.
