How Oregon’s Waterfalls Work
Water meeting rock is more than a view. It is a process that reveals how a stream negotiates the ledges and benches built by past volcanism, faulting and erosion. Across Oregon, those controls decide whether a river plunges in a single sheet, breaks into tiers, or spreads as a curtain. What you see at the brink and in the spray is a moving readout of flow, wind and season.
Storm cycles shift that readout fast. Heavy rain ramps discharge, wakes side channels, stirs fine sediment and pushes mist into places that stay dry in fair weather. This page routes you to the article that tracks those cause-and-effect changes at a specific waterfall so you can interpret what the weather is doing to the fall you plan to visit.
