In this part of the state the standard base is 3/4 minus, a crushed rock graded from 3/4 inch down to fines that compacts and locks up under a drive.
This is Basin and Range, Klamath and Owyhee Country ground: fault-block basins filled with lake-bed silt, alkali flats and playa ground, with basalt rims standing above them. That ground decides what you put on top of it.
Ground Conditions Across Harney County
Across the Basin and Range, Klamath and Owyhee Country, the working season is short and bounded by hard frost at both ends. Frozen ground and soft spring basins both stop compaction, so timing a delivery matters as much as the material.
Precipitation runs under 15 inches a year, but the basins are closed and have nowhere to send water. Playa and alkali ground stays soft and holds surface water after snowmelt.
Wind moves bare playa and alkali flats, and sheet flow comes off the rims into the basins during snowmelt and summer storms. That is where slope protection and open drainage stone earn their place.
Cold winters at 4,000 feet and above bring sustained freezing, with recorded lows across this country running from 20 to 34 degrees below zero. Klamath County publishes 24 inches below grade for foundation design, matching the Oregon step for 4,000 feet and above.
Footing depth is set by the building official, not by your gravel order.
Materials Delivered in Harney County
Oregon names aggregate by top size. A minus notation means the material keeps its fines and compacts; clean or open means the fines are screened out and water moves through it.
That pair is the whole game.
3/4 minus is the one to know first.
Oregon specifies base material by top size with a minus notation, and the Oregon Standard Specifications for Construction set dense-graded base aggregate in Section 02630.10 at sizes of 2 1/2 inch - 0, 2 inch - 0, 1 1/2 inch - 0, 1 inch - 0 and 3/4 inch - 0.
Section 00641.10 states that base aggregate is dense-graded unless otherwise specified. Section 02630.11 covers open-graded aggregate, the clean, fines-free material.
Order Driveway Gravel for surfacing an existing drive, and Walkway Gravel for a finer, walkable path surface.
Choosing the Right Material
Crook County sits on Central Oregon and the High Lava Plains, the youngest volcanic ground in Oregon. Young basalt with pumice, cinder and ash soils around Bend, Redmond and Sisters, and thin soil over hard rock along the rims.
That ground is different from the lake-bed silt and playa here, so a base course there sits on a very different subgrade.
Lake County and Malheur County share this ground region. Fault-block basins filled with lake-bed silt, alkali flats and playa ground, basalt rims standing above them, and old lake sediments in the Klamath Basin.
The ground is the same, and the same rules apply: a minus base that compacts, and open stone where water has to move.
Match the material to the job. A compacted base takes 3/4 minus.
A drain, drywell or downspout run takes drain rock or 3/4 clean. Bedding under pavers takes 1/4 minus.
Rounded decorative stone takes Natural Pea Gravel or river rock, and bank work takes riprap or large river rock.
