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 enc

GNSS site LKWY, which was visited in September 2020 to install new GNSS equipment and upgrade the communications for improved data quality. The site is now capable of collecting several times more observation data then was possible with the original older equipment.

High-resolution images of Fern Lake from different seasons. North is up. Fern Lake is about 1 km across from east to west. Red arrows in the winter image point to large zones of open water, indicating either nearshore springs or underwater hydrothermal vents, but there are also many smaller zones of open water that are conspicuous.

On September 3, USGS HVO geologists visited fissure 7 of Kīlauea's 2018 lower East Rift Zone eruption. Geologists investigated and documented vent features, and collected samples for ongoing analyses of 2018 eruption dynamics. Fountains from fissure 7 left a hole over the vent area.

Photo of Kīlauea's 2018 lower East Rift Zone eruption fissure 7, from Hookupu street and looking west. The rampart is surrounded by fissure 8 lava. This view is of the back side of the rampart; lava fountains erupted on the opposite side of the rampart.

View of the front side of fissure 7 rampart, erupted during Kīlauea's 2018 lower East Rift Zone eruption. Red oxidation is present in lower layers within the rampart. Golden shelly pāhoehoe from fissure 8 surrounds the rampart.

On September 3, USGS HVO geologists also visited fissure 21 of Kīlauea's 2018 lower East Rift Zone eruption. Geologists investigated and documented vent features, and collected samples for ongoing analyses of 2018 eruption dynamics. View of fissure 21 from the northeast. A small hole has formed from collapse of the rampart.

The UNAVCO-operated geodetic infrastructure located in Yellowstone National Park consists of over a dozen continuously operating geodetic sites. Most of these sites stream real-time data to the UNAVCO data center. After the September 2020 maintenance trip, there are now 8 fully upgraded GNSS sites (red square) located in the park.
