The U.S. Forest Service has withdrawn snowmobile use maps for two national forests in Idaho and part of another in Wyoming after environmental groups said the maps violate the federal agency's regulations and environmental laws.

The Forest Service last week withdrew Over-Snow Vehicle Use Maps for the Payette National Forest and Boise National Forest in Idaho.

The agency also withdrew the map for the Teton Division of the Bridger-Teton National Forest in Wyoming.

But the agency says there will be no change to over-snow motor vehicle use in those areas this winter.

Winter Wildlands Alliance and others in a lawsuit filed earlier this year say the maps are outdated and aren't restrictive enough for snowmobiles that have become more numerous and powerful in recent years.
