The useful part

Instead, it offers a striking oblique 3D view where the surface of the earth has been sliced open like a layer cake. DrillerDB has managed to map the data to standard USGS lithologic classifications. The resulting Underground Viewer renders these records as color-coded, vertical lithology blocks.

How it works

  • Where data thins out or evidence runs dry, the cross-section fades to black rather than inventing speculative layers.
  • Rising above the horizon is standard aerial imagery draped over USGS 3DEP elevation data, but the real star of this map lies directly underneath: a volumetric 3D cross-section revealing the actual...
  • In these 3D cross sections you can see distinct beds of clay, sand, gravel, shale, and limestone stacked continuously under the ground.
  • Where local well logs offer direct physical evidence, the model draws the geological faces as solid colors.
