Nature Trail

The Walk

From Leif Erikson, the trail sets off along the creek — Houle’s first quarter-mile — before it turns uphill for the two-thirds of a mile that climbs to Fire Lane 1, gaining about 350 feet along the way. It’s easy-to-moderate going, gentle by park standards, and if you’re descending it as a loop return you’ll barely notice the grade at all.

The dam comes first, near the bottom. Give it a look. It doesn’t announce itself — no plaque tells you what it is anymore — but once you know, the shape reads clearly: a low earthen bank thrown across the gully, the pond behind it long since filled with a century of leaves and silt.

Local Lens: a forest that had to fight fire Rocking Chair Dam is a small monument to an old worry. Portland’s west hills are steep, dry in late summer, and pressed right up against a city — a wildfire here has never been hypothetical. The little reservoir this dam once held was insurance, water stored close to where crews might need it. The dam failing quietly into the creek isn’t neglect so much as the forest outlasting the emergency it was built for.

Past the dam the trail leaves the creek and works up out of the gully under mossy vine maples — the tangly, low-limbed maple that thrives in exactly this kind of damp, shaded fold — then climbs a ridge carpeted in Oregon grape, the holly-leaved shrub whose leaves flush wine-red in the cold months. It dips into a second gully, crosses the creek on footbridges, and makes two switchbacks up to a broad ridge crest where a few picnic tables and a bench mark the old level bench — the spot where the shelter once stood. From there it’s a short last pull to the grassy meadow beside Fire Lane 1.

Forest Skill: read a nurse log On these slopes, watch for a fallen fir or cedar with a whole garden growing along its spine — moss, licorice fern, hemlock and huckleberry seedlings all lined up on the log like passengers on a bench. That’s a nurse log, and it’s doing the most important job in the forest: a dead trunk holds water like a sponge and lifts young seedlings above the crowded duff, so a tree that fell decades ago is quietly raising the next generation. A nurse log is what happens when a tree decides retirement is for quitters.

Kid Quest: be the missing signs This trail used to have numbered posts that told you what to look at. They’re gone — so your job is to put them back. As you walk, call out your own stops: post one, the sneaky dam; post two, the biggest tree you can’t reach around; post three, a log with a garden on it; post four, the reddest Oregon-grape leaf. Whoever finds the best stop gets to name the trail’s mascot.

Before you go

This is a gully, and gullies hold water. From the first serious rains of fall through spring the tread turns muddy and the footbridges get slick, so wear shoes you don’t mind trashing and stay in the center of the trail even where the center is the messy part — skirting the puddles is how a narrow trail quietly widens and undoes the slope it’s cut into.

There’s no trailhead here and no facilities on the trail, so sort your logistics before you leave the car: the Nature Trail is a piece of a larger walk, not a destination you drive to. Keep it a daylight outing, both because the gully goes dark early under the canopy and because the Fire Lane 1 lot you’ll likely use locks its gate at night. Dogs on leash, and leave the wheels behind — this one’s foot-only, which is a large part of why it stays so quiet.

Stop for a second at the old bench near the top, where the shelter used to be. There’s nothing there now but tables and trees and the sound of the creek down in the fold. The trail spent decades trying to explain this place to people. Turns out it didn’t need the words.
