GeologyPayne Cliffs formation - sandstone and siltstone
Vault/Borehole ConditionsThe equipment is located in a side adit of a hard-rock mine approximately 100 meters from the entrance. Overburden is approximately 50 meters. The sensors are located on a concrete pier covered with 4" of rigid foam insulation.
The datalogger, dial-up modem, and fiber optic modems are located in a plastic garden shed about 8 meters from the pier. Batteries are located in a large plastic storage box next to the shed. The tunnel entrance is covered with a hinged steel grate to allow free passage of bats. Humidity is 100% outside the enclosures. Telemetry is through 300 meters of fiber optic cable connected to a satellite system.
