The area outlined in orange marks the surface boundary. The area includes, the Ross Complex—marked in light green, and the Yates Complex—marked in dark green. The Sanford Lab Homestake Visitor Center is marked by the purple overlay.

Underground at Sanford Lab
The main level for science is the 4850 Level, which can be accessed by the Yates and Ross Shafts. But Homestake carved out over 370 miles of shafts, drifts, and ramps. Sanford Lab maintains about 12 miles for science activities.
Current science facilities at the 4850 Level
There are two main science areas currently on the 4850 Level. Existing facilities are colored blue.
The Davis Campus near the Yates Shaft houses laboratories for:
The Majorana Demonstrator—neutrinoless double-beta decay.
The Large Underground Xenon first generation dark matter experiment.
The Ross campus near the Ross Shaft has facilities for:
Low Background Counting at BHSU Underground Campus.
CASPAR (Compact Accelerator System for Performing Astrophysical Research.
The Majorana Demonstrator electroforming laboratory.
Future science facilities at the 4850 Level
Future laboratories are colored green.
At the Davis Campus:
LZ, a second generation dark matter experiment will replace LUX.
At the Ross Campus:
The Deep Underground Neutrino Experiment or DUNE will be four 10kT liquid argon detectors. DUNE is part of the Long Baseline Neutrino Facility.
A proposed experiment hall to that could house a third generation 1 Ton neutrinoless double-beta decay experiment and a third generation dark matter experiment.
