DENVER  In much of the nation, “monument” is an innocuous word, conjuring up images of historical figures cast in bronze or road-side plaques few stop to read.

In the West, though, it’s a fighting word, bound up for years with simmering resentments against the federal government and presidential powers. The feeling dates to the days when, with the stroke of a pen, Theodore Roosevelt declared lands he wished to protect as national monuments under the American Antiquities Act.

A new monument fight erupted this week when Representative Rob Bishop, Republican of Utah, said he had uncovered a “secret” Interior Department memorandum suggesting that the federal government was considering national monument designation for 14 huge blocks of land in nine states from Montana to New Mexico.

A spokeswoman for the Department of the Interior, Kendra Barkoff, said the list was not secret at all, but simply a “very, very, very preliminary,” internal working document resulting from a brainstorming session that Interior Secretary Ken Salazar, a Democrat and former senator from Colorado, had requested about the lands in the West.
