The publications documents the drilling of two 150 m deep boreholes in the Seattle, WA area. It presents, describes and compares borehole stratigraphy, down hole geophysical logs and compressional (Vp) and shear-wave (Vs) velocity measurements acquired from both boreholes. Velocity information is described in terms of the glacial and non-glacial stratigraphy of the area.
