A Utah congressman long unhappy with the authority given presidents under The Antiquities Act to establish national monuments has introduced legislation that would extensively rewrite the century-old act. If enacted, the rewrite would limit the purposes for which monuments could be created, require environmental review, and allow presidents to reduce the size of monuments without congressional action.

Last month, the National Park Service (NPS) celebrated its 100th birthday. In the days leading up to the celebration, NPS director Jonathan Jarvis said that his agency’s goal for the centennial was “to create the next generation of visitors, supporters, and advocates for our national parks and our public lands.”
