The paper describes logged blow counts, lithology, and interval Vp and Vs in three boreholes, the latter at 0.91 m intervals. The general stratigraphy includes Pliestocene loess atop Pliocene-Pliestocene clay and sand, overlying Tertiary deltaic marine deposits. They contain Holocene Mississippi floodplain sand, silt, and gravels.
Velocities correlate generally well with lithology and with velocity estimates published by others.
Average values are those quoted in other studies.
