Photo location: |
Birchwood soils are moderately well drained soils formed in sandy eolian and/or fluvial material underlain by loamy dense till. This profile has the following morphology: 0-12 inches, Ap horizon -loamy sand. 12-20 inches, Bw1 horizon -loamy sand. 20-34 inches, BC horizon -gravelly loamy sand with many redoximorphic features (seasonal high watertable within 24 inches), 34-65 inches, 2Cd -gravelly fine sandy loam, very firm basal till, many redoximorphic features.
The 2Cd horizon has a vertical desiccation crack (gray surrounded by bright colors), above-right is a close up of the cracks:

Potential Inclusions:
Moderately well drained Woodbridge, Scituate, and Newfields soils
are on similar landforms. Poorly drained Norwell, and Ridgebury soils are on lower elevations and along drainage-ways.
Well drained Paxton, Poquonock and Montauk soils are on convex
slopes and on higher elevations.
