Qhl Natural Levee Deposits (Holocene) – Loose, moderate- to well- sorted sandy or clayey silt grading to sandy or
silty clay. Levee deposits are generally well drained.
Qhfp Floodplain Deposits (Holocene) – Medium to dark-gray, dense, sandy to silty clay. Lenses of coarser material
(silt, sand, and pebbles) may be locally present.
– Organic - rich clay to very fine silty-clay deposits occupying the lowestQhb Floodbasin Deposits (Holocene)
topographic positions between Holocene levee deposits or Holocene floodplain deposits.
Qhaf Alluvial Fan Deposits (Holocene) – Brown or tan, medium dense to dense gravelly sand or sandy gravel that
grades upward to sandy or silty clay. Near the distal fan edges, deposits are typically brown, medium
dense gravelly sand or clayey gravel that grades upward to sandy or silty clay.
