Most Yellowstone Park Roads Closed to All Vehicles - NPS
Most Park Roads Closed to All Vehicles Most roads are closed to prepare for commercially-guided snowcoach and snowmobile travel during the winter season, which will begin December 15 (weather depending).

The only road generally open year-round to regular vehicles is from the North Entrance at Gardiner, Montana, through the park to Cooke City, Montana (via Tower Junction). Most park roads are closed to regular vehicles from early November to late-April, and are open to limited oversnow travel (commercially-guided snowmobiles and snowcoaches) from mid-December to mid-March.

A mission to repair one of the most interesting GPS monitoring stations in Yellowstone - Caldera Chronicles

When they go offline, a lot of preparation and effort is necessary to bring them back to functionality. Yellowstone Caldera Chronicles is a weekly column written by scientists and collaborators of the Yellowstone Volcano Observatory. This week's contribution is from Michael Poland, geophysicist with the U.S. Geological Survey and Scientist-in-Charge of the Yellowstone Volcano Observatory. The continuous GPS station at White Like, designated WLWY (GPS stations are always given 4-character codes), is one of the most interesting in all of Yellowstone National Park. The station was installed in 1999 on the Sour Creek resurgent dome —one of two uplifted areas of Yellowstone caldera that formed due to magma ...
