There is an effort by a group of US senators that is intended to allow carrying firearms in National Parks. You can find the article on the front page of the Anchorage Daily News:

WASHINGTON -- Both of Alaska's U.S. senators have signed a letter asking the Interior Department to repeal federal gun rules for national parks and wildlife refuges, saying that the existing guidelines are "confusing, burdensome and unnecessary."
If federal officials agree, the result could be people being able to legally carry loaded guns onto federal lands in Alaska where they're now banned, including much of Denali National Park.
The letter was drafted by U.S. Sen. Mike Crapo, R-Idaho, who asked Interior Secretary Dirk Kempthorne to change rules that prohibit visitors to most national parks and wildlife refuges from carrying operable, loaded guns.
