Explore the new WGNHS Data Viewer.
WGNHS Data Viewer, our new interactive map, provides online access to two of our rapidly growing collections—geophysical logs and Quaternary core.
Geophysical logs are used to understand the subsurface by geologists and hydrogeologists, municipal water utility operators, and by water-quality regulators. The data viewer includes over 1,000 individual geophysical logs from over 700 boreholes. Data includes gamma, caliper, normal and single-point resistivity, fluid temperature and conductivity, and optical and acoustical borehole images. Logs are downloadable as PDFs and LAS (log ASCII standard, an industry standard for well log data) files.
The Quaternary core collection provides locations of and types of data collected at more than 500 sites drilled in unconsolidated geologic materials. Information about the data may include depth of boring, drill method, and available analyses, such as grain size, if subsample testing was performed, and if high-resolution core photos have been taken.
For more information about these collections, contact the WGNHS Archivist at 608-262-1705.
