Detailed Description
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.
