The inside of a Yellowstone borehole seismometer equipment enclosure
The inside of a borehole seismometer equipment enclosure is full of batteries, cables, data communications equipment and data recording instruments. Some of the geodetic infrastructure in Yellowstone National Park is colocated with seismic equipment. In this case, the communications downlink radio for the GNSS station is housed with the borehole enclosure. This site was visited in September 2020 in order to repair a power system failure.
