Materials for Pilot Rock Projects

Decorative rock carries the look of a yard here. Use it for beds, borders, dry creek beds and ground cover where you want stone that stays put and reads as a finished surface.

Willamette River Rock is rounded, water-worn stone for decorative beds and borders. Large River Rock suits dry creek beds and splash pads under downspouts, where small stone would wash out.

3/8" Natural Pea Gravel gives paths, play areas and dog runs a smooth rounded surface. Bark dust covers beds and tree rings and suppresses weeds.

For a driveway or pad, 3/4 minus is the Oregon base. It is crushed rock graded 3/4 inch down to fines, so it compacts and locks up.

3/4 Minus goes under drives, parking pads, shop floors and shed bases.

Drainage work needs open stone instead. Drain Rock is washed and open for French drains, footing drains, drywells and downspout runs.

3/4" Crushed Stone is angular rock with the fines screened out, for drainage trenches and retaining wall backfill.

For planting, Top Soil handles lawns and finish grading, and Garden Soil fills raised beds where native ground is too tight to plant into. Washed Sand beds pipe and levels under flatwork.

Ground and Conditions in Pilot Rock

Columbia River Basalt flows sit under wind-laid loess across the Columbia River Gorge and Plateau. Deep silt covers the wheat ground, and soil goes shallow where the basalt comes near the surface.

Precipitation runs 8 to 15 inches a year, so volume is not the problem. Loess turns greasy when wet, sheds water fast when dry, and runs off frozen ground in winter.

Wind moves bare loess, and summer thunderstorms cut rills and gullies on cultivated slopes.

That ground punishes an under-built base. Silt and clay shift under a load, so a drive or pad built on native soil alone will not hold.

3/4 minus compacts into a graded layer that spreads the load instead.

Water needs somewhere to go. Drain rock and 3/4 clean move it away from footings, trench bottoms and wall backfill rather than letting it sit against the soil.

The working season runs long, bounded by hard frost at one end and summer dust at the other. Water for compaction often has to be hauled on the plateau.

Winters run cold and dry with a hard east wind through the Gorge, and ground frost goes deeper here than west of the Cascades. Frost depth is set by the county building department.
