# SUPPLEMENTARY INFORMATION: 

This document presents and analyzes 7 alternatives for winter use management in Yellowstone National Park (YNP), Grand Teton National Park (GTNP), and the John D. Rockefeller, Jr., Memorial Parkway (the Parkway). 

Alternative G, the preferred alternative, emphasizes clean, quiet access to the parks using the technologies available today. It would allow over-snow access on all routes currently available via NPS-managed snowcoach only. Other key changes in recreation opportunities are: eliminating winter plowing on the Colter Bay to Flagg Ranch route, making Flagg Ranch a destination via over-snow transport, and eliminating all winter motorized use on Jackson Lake. This alternative addresses the full range of issues regarding safety, natural resource impacts, visitor experience and access. It addresses the issues in a way that would make it necessary for local economies to adapt, and for snowmobile users to access the parks using a different mode of transport. Under alternative A-No Action, current use and management practices in the parks and Parkway continue. The concept under alternative B provides a moderate range of affordable and appropriate winter visitor experiences. Air quality and oversnow motor vehicle sound would be addressed, and by the winter of 2008-2009, strict emission and sound requirements would be required by all oversnow vehicles entering the parks. This alternative also emphasizes an adaptive approach to park resource management, which would allow the results of new and ongoing research and monitoring to be incorporated. Alternative C maximizes winter visitor opportunities for a range of park experiences. Alternative D stresses visitor access to unique winter features in the parks. This alternative emphasizes clean, quiet modes of travel, visitor activities focused near destination areas, and a minimization of conflicts between nonmotorized and motorized users. Under alternative E the protection of wildlife and natural resources is emphasized while allowing park visitors access to a range of winter recreation experiences. Alternative E uses an adaptive planning approach that allows new information to be incorporated over time. Alternative F stresses the protection of wildlife resources by focusing winter visitor activities in YNP outside important winter range for large ungulate species, and closing north and west roads to winter use. For GTNP and the Parkway, this alternative emphasizes the protection of all resources by focusing developments, oversnow motorized trails and zones, and nonmotorized trails and zones in certain areas, while still allowing park visitors opportunities for a range of winter recreational experiences. 

The details and impacts of the alternatives are described in this document. They include major long-term beneficial improvements to the protection of geothermal winter range and other park resources, some adverse effects from visitor use activities, and major beneficial improvements to the desired visitor experience for solitude, clean air, and natural quiet. These impacts vary by alternative.
