Mayfly Falls

Mayfly Falls West Fork Carcus Creek apiary columbia county oregon
Mayfly Falls

Height and type: 60-80 foot horsetail falls, possibly seasonal.

Water body: West Fork Carcus Creek

Access: There is no direct route accessible to the public. We found it after 5 miles of hiking on various logging properties with significant off-trail stretches to make connections. Do not attempt unless you are with a partner, have good maps, and are experienced in off-trail navigation. The final approach was a 400+ foot bushwhacking descent on a steep slope with no phone reception if you got yourself into trouble.

Trip report: Introducing Mayfly Falls

Property status: The falls are on private Weyerhaeuser land. They allow walk-in access with permits.

Notable Wildlife: Roosevelt elk, white-footed vole, american dipper, stream amphibians

Interesting History: The forest has been clearcut to within about 20 yards of the creek below the waterfall and all the way up to the creek above it. As a result, the creek’s water is silty and unconducive to aquatic life. Oregon previously had the most lax logging buffer regulations of any state in the region, but the Oregon Private Forest Accord was signed into law in 2022, extending the buffer distance within which logging along streams cannot occur. You can find further details of the Private Forest Accord in this pdf, or in the longer report here.
