Kwanesum Falls is the largest waterfall along Moffett Creek, with a drop of about 145 feet in a narrow recessed amphitheater. There is no developed access to the falls, and the terrain around it is so rugged that the only possible access to the falls requires technical climbing skills.
- Kwanesum Falls is the Proposed name of this waterfall.
- Known Alternate Names: Middle Moffett Falls
The falls have no official name. The name Kwanesum has been proposed by two intrepid Portland area waterfall hunters who are thought to be the first to see the falls from the ground. Kwanesum is a Chinook word meaning "forver, eternity or always".
