Soil and climate diagrams
Schematic block diagram, not to scale: the top shows the relief and the front face a cross-section, coloured by soil and rock type.
- The Russian River Valley was defined as a cool coastal growing area into which early-morning fog intrudes; later work found that much of the summer fog is blown in through the Petaluma Gap, north towards Santa Rosa and north-west towards Sebastopol.
- In the coastal ranges of western Sonoma, high sites stand above the fog layer, while ridgelines shelter lower slopes from the heaviest marine fog.
- Goldridge soils are deep, moderately well-drained fine sandy loams formed from weakly consolidated sandstone on rolling uplands; the marine sandstone of the Wilson Grove Formation crops out west of the Santa Rosa Plain and dips beneath it, under younger river, lake and alluvial deposits.
