Scientists install a semipermanent GPS station in Yellowstone National Park.  These stations, which are not radio-telemetered, are typically installed in May and recovered in October, when the data are downloaded and processed.  These stations help to supplement the continuous GPS network in the Yellowstone area.

Scientists and collaborators of the Yellowstone Volcano Observatory meet in Mammoth Hot Springs in May 2022 to discuss the protocols for responding to a geological event in Yellowstone National Park.
