These are your new national parks

A series of proposed revisions of National Park policy has created a furor among present and former park officials who believe the changes would weaken protections of natural resources and wildlife while allowing an increase in commercial activity, snowmobiles and off-road vehicles....

"They are changing the whole nature of who we are and what we have been," said J.T. Reynolds, superintendent of Death Valley National Park. "I hope the public understands that this is a threat to their heritage. It threatens the past, the present and the future. It's painful to see this."

The potential changes would allow cellphone towers and low-flying tour planes and would liberalize rules that prohibited mining, according to Bill Wade, former superintendent at Shenandoah National Park in Virginia....

Members of the group said they were particularly concerned about policy changes that would allow snowmobiles to travel over any paved road in any national park in the winter; elevate certain activities already occurring in some parks, such as grazing and mining, to "park purposes" -- which would ensure their continuation; and change the acceptable level of air quality from "natural background" to air that has been altered by human presence.
