Geologic Map of the Poverty Bay 7.5' quadrangle, King and Pierce counties, Washington

“…1). Booth and Waldron (2004) noted three other localities of reversely magnetized sediments along the Puget Sound coastline just north of the quadrangle boundary.…”

“…The east-central Puget Lowland is underlain by Eocene to Miocene volcanic and sedimentary rocks (Yount and Gower, 1991;Tabor and others, 2000). In the Poverty Bay 7.5' quadrangle, these rocks are not exposed at the ground surface; the nearest surface exposures are about 6 mi (10 km) north in the Des Moines 7.5' quadrangle (Booth and Waldron, 2004). From very limited borehole data, this Tertiary bedrock lies between 400 and 600 m below the ground surface in the map area (Jones, 1996).…”

Geologic map of the Suquamish 7.5' quadrangle and part of the Seattle North 7.5' x 15' quadrangle, Kitsap County, Washington

“…This unit is largely equivalent to coarsegrained, pre-Fraser-age deposits mapped on recent maps of nearby areas (for example, unit Qpf c in Booth and Waldron, 2004). It is likely that unit Qpv locally includes sand, silt, and clay of early Vashon age as well as beds that, with better outcrop, could be assigned to units Qup, Qpog, Qpor, and Qpv f .…”

“…Recently published maps of the central Puget Lowland (for example, Booth and Waldron, 2004;Troost and others, 2005) have mapped equivalent strata as "Vashon advance outwash deposits (Qva)". We have revived the nomenclature of Mullineaux and others (1965) to emphasize that (1) in the Suquamish quadrangle, this unit is predominantly sandy and lacks the associated gravel layers found elsewhere within the Booth and Waldron (2004) and Troost and others (2005) unit Qva and (2) we have mapped a lithostratigraphic unit with its attendant uncertainties, rather than a time-process unit.…”

Sustainable Stormwater Management Using Underground Injection Control Wells: A Case Study

“…Soils in the site vicinity are characterized as Quaternary glacial till overlying advance outwash deposited by the most recent continental glacial advance (Booth and Wisher 2007). Glacial till is an overconsolidated mixture of gravel, sand, silt, and clay that was deposited and overridden by the prehistoric glacial ice mass (Minard 1983).…”
