Lane County, OR

Diamond Creek runs across a steep cliff where the creek widens to a good 75 feet as it veils down jagged, grooved basalt formations. Most sources cite this waterfall as standing about 90 feet tall, but topographic maps show a well-defined drop of about 120 feet.

The origin of the name of Diamond Creek is unknown, but there are two possibilities. Nearby Diamond Peak was named for John Diamond of Coburg, who was among a party opening a road along the Middle Fork Willamette River for immigration. Either Diamond Creek was given the same name, or the creek was named after Diamond Peak (either way, it was named for the same person).

The falls are viewed via a 3.4 mile loop trail that offers wide views of Salt Creek Canyon.
