Grand Teton National Park News Release
National Park Service Grand Teton PO Box 170 U.S. Department of the Interior National Park Moose, Wyoming 83012 FOR IMMEDIATE RELEASE Jackie Skaggs/307.739.3393 January 08, 2010 10-01 Grand Teton National Park News Release Environmental Assessment Available for Public Review on Site Work for Grand Teton National Park Headquarters Rehabilitation Project Grand Teton National Park Superintendent Mary Gibson Scott announced today that the Moose Headquarters Rehabilitation Site Work Environmental Assessment (EA) is now available for public review. This EA will be open to review for 30 days, from January 11 through February 9, 2010. The National Park Service (NPS) proposes to perform site improvements that are designed to enhance visitor services and address employee health and safety deficiencies at Grand Teton National Park’s headquarters area in Moose, Wyoming. The site work would restructure vehicle/pedestrian access points, promote better traffic flow, reduce user-created trails and consolidate pedestrian walkways, and improve way-finding throughout the Moose headquarters complex. The purpose of the proposal is to upgrade and improve conditions in a way that enhances visitors’ experiences while providing a safe, healthy, and functional working/living environment for park employees and their families. The NPS preferred alternative involves the reconfiguration of vehicle and pedestrian traffic within the park administrative area and the Moose river landing access, the removal of several temporary buildings, and restoration work targeted at providing appropriate stormwater management. The proposed improvements are designed to increase visitor and employee safety, refine parking and traffic flow patterns, reduce the built environment, and improve water quality while still preserving the character of the area and protecting natural and cultural resources. -

Exploring Grand Teton National Park
05 542850 Ch05.qxd 1/26/04 9:25 AM Page 107 5 Exploring Grand Teton National Park Although Grand Teton National Park is much smaller than Yel- lowstone, there is much more to it than just its peaks, a dozen of which climb to elevations greater than 12,000 feet. The park’s size— 54 miles long, from north to south—allows visitors to get a good look at the highlights in a day or two. But you’d be missing a great deal: the beautiful views from its trails, an exciting float on the Snake River, the watersports paradise that is Jackson Lake. Whether your trip is half a day or 2 weeks, the park’s proximity to the town of Jackson allows for an interesting trip that combines the outdoors with the urbane. You can descend Grand Teton and be living it up at the Million Dollar Cowboy Bar or dining in a fine restaurant that evening. The next day, you can return to the peace of the park without much effort at all. 1 Essentials ACCESS/ENTRY POINTS Grand Teton National Park runs along a north-south axis, bordered on the west by the omnipresent Teton Range. Teton Park Road, the primary thoroughfare, skirts along the lakes at the mountains’ base. From the north, you can enter the park from Yellowstone National Park, which is linked to Grand Teton by the John D. Rockefeller Jr. Memorial Parkway (U.S. Hwy. 89/191/287), an 8-mile stretch of highway, along which you might see wildlife through the trees, some still bare and black- ened from the 1988 fires. -
