Mole hills give a good horizontal profile of the soil. This one shows more silt and clay then what much of the Lystair series shows, it probably should be mapped as Cloquallum Silt Loam and not Lystair.
The producing vines are on Lystair sandy loam soil (some Cloquallum silt loam too)
Here is the 1960 description by:
SOIL SURVEY OF MASON COUNTY, WASHINGTON
Report by A. 0. Ness, Soil Conservation Service, United States Department of Agriculture
"The Lystair series consists of somewhat excessively
drained, brown, sandy soils that occupy hilly kettles and
kames and nearby level outwash plains. They have developed
from nearby gravel-free, loose, sandy glacial drift
deposited mainly by out wash waters. The rainfall is 60 to
90 inches a year. The vegetation is a forest consisting
mainly of Douglas-fir and some thick stands of lodgepole
pine, and there is an understory of kinnikinnick, Oregongrape,
bracken fern, and salal.
The soils are somewhat excessively drained and are
droughty. They have a low capacity for available moisture.
Lystair soils occur in the western part of the county in
association with the Shelton and Grove soils. They have
a redder profile than the Indianola soils. In addition,
they have developed from more basic parent material,
under higher rainfall, and have darker sandy subsoils and
substrata."
Our water wells go to a depth of 70 feet and there hit basalt rock. There is no gravel all the way down to the basalt. The well water table doesn't drop when tested in late August. Lystair soil is a sandy loam. Future vineyard sites here could be on the Cloquallum silt loam, Maytown silt loam and Grove gravely loam.
