Summary

Records in this collection are classified into one of four categories that best characterizes the data contained within the borehole record. The classifications are: Geotechnical: Boreholes and pits created with the intent to gain a detailed understanding of the subsurface lithology and soil or rock properties therein. These records have additional data beyond lithologic descriptions including penetrometer resistance, shear and strength tests, density measurements, etc. Lithologic borings: Boreholes are drill solely for the purpose of identifying subsurface lithology. Material testing techniques were not used (or the results are not provided) to allow for a more detailed understanding of subsurface material properties. Test pits: Generally [...]

Purpose

These data are intended to be used by used by geologists, engineers, planners, private-sector geoscientists, and the general public to identify geologic hazards, perform analyses of slope stability, downslope and downstream impacts, storm water management, and identify mitigation opportunities for construction or other land-development projects. Subsurface data is also used in mining, oil and gas exploration, carbon sequestration, and geothermal exploration.
