Puget Sound defines Washington; Oregon projects a riparian state, where names including Willamette, Deschutes, and McKenzie send waterfall enthusiasts over the top. Travel through the Willamette Valley and frothy cascades taunt you from every eastbound turnoff, boasting as many as 10 aquatic plummets along a lone-forested stroll. Oregon’s North Cascades alone offer 51 different waterfalls, some a long hike’s reward, but many are within a polished river stone’s throw of the parking lot.

Trek farther into the South Cascades to discover 78 more tumbles. Even Eastern Oregon, its high altitude basin dominated by shrub-steppe environment, has more than 20 cascades to cool the observer in this near-desert clime. Cleaving the Great Basin with its basalt scalpel, the Columbia Gorge’s Oregon face trips up river flows more than 50 times.

From Washington to California, these Cascades provide the pugilist’s ring for two of nature’s heavyweights—water and volcanic eruption—which have shoved each other like school bullies for five to seven million years, since the “modern” peaks drove skyward.

I bypass Silver Falls State Park, where the Trail of Ten Falls/Canyon Trail carries hikers along a moderate path to see cataracts ranging from 27 to 177 feet, four of which invite them to slip behind the stream. My travels parallel the McKenzie River from Eugene to Sisters via SR 126, where the Koosah (“Sky”) and Sahalie (“Heaven”) waterfalls signal the endpoint of two distinct 6,000-year-old basaltic lava flows.

A three-mile loop trail connects the two waterfalls; the Koosah broad shouldered and squat, the Sahalie lean and tall. The trail continues from Koosah Falls through the Douglas fir forest to the Carmen Reservoir, which quickly subdues the corset-tightened current that, 100 yards prior, frothed violently at its confinement like Bram Stoker’s Renfield during a full moon.

The mist rises from the Koosah’s tempestuous descent, covering the trees with mossy linen and saturating the ground like the tropics, emphasized by the presence of native deer’s head orchids, a.k.a. fairy slippers or calypso orchids.

The gentle 400-foot climb to Sahalie Falls flows without obstacle, save for pauses along the trail to let mountain bikers, another ubiquitous species along the McKenzie River Trail, pass. Sahalie stands tall to Koosah’s broad girth, a shard of earth wedged like a railroad spike between the bifurcated cascade. A mossy amphitheater awaits the crashing water, a verdant backdrop to each sunny day’s rainbow projection.

As with judging most geologic history, it’s difficult to declare a winner between aquatic and basaltic foes. The lava has damned Clear Lake just a few miles southeast of Sahalie Falls and the gorge between and below the waterfalls restrains the current like a child who’s jailed bees in a Mason jar. But the lava’s victorious boast is loudest at Tamolitch Pool, where the basaltic flow drove the McKenzie underground with Hades resolve.

Still, the riparian resolve can’t be measured in a mere 6,000 years because, unlike the basalt flow’s roundhouse, the river’s infinite jabs at its jailor will one day yield freedom, even if the bell fails to ring for millennia. Let’s just call it a draw, at least for now.
