The Virginia Department of Transportation (VDOT) Geologic Sections dataset consists of site-specific, large-scale geologic cross-sections (composite sheets). These sections were acquired from VDOT in order to save them from disposal. There are 5,500 geological profiles created for highway construction projects containing extensive core, auger and split-spoon logs at scales of 1:50 and 1:100 providing a unique record of subsurface geological and geotechnical data along roadways throughout Virginia. The thousands of feet of vertical subsurface data represents millions of dollars of investment in data acquisition by VDOT. The sections are useful as indicators of subsurface geology in large parts of Virginia. ...

The Florida Geological Survey (FGS) holds a collection of over 9,000 lithologic descriptions of cores and cuttings from boreholes throughout Florida. This includes legacy logs previously stored in a file format requiring a DOS program to decode. Paper copies of a majority of legacy lithologic logs are stored in 150 large, green loose-leaf binders collectively named “Greenbooks,” (see the Collection of Borehole and Sample Reference Documents from Florida). The legacy files represent 60% of the collection and are currently being prepared for import into the FGS’s database to be made publicly available. The remaining 40% of the collection exist in various formats (both coded and decoded), which the FGS is working to...

The Alaska Division of Geological and Geophysical Surveys (DGGS) surface sample collection consists mostly of hand samples collected during projects involving DGGS geologists, but also includes pulps and residues. The accuracy of the sample metadata differs based on the time frame of the project that originated the samples. The DGGS projects fall in two categories: (1) legacy projects where sample locality information was not recorded systematically in either a physical or digital format and (2) recent and current projects where sample locality information has been recorded in digital databases. This collection consists of 123,808 rock samples as of 2020, though not all are accessible to the public or have location...
