Interior Secretary Ryan Zinke says he plans to visit one or both of Nevada’s national monuments – currently under review by his department – by the end of July.

Zinke recently recommended shrinking the boundaries of Bears Ears National Monument in Utah, sparking concern that he might do the same for Gold Butte and Basin and Range in Nevada. Darren Daboda, chairman of the Moapa Band of Paiute Indians, says the monuments are an important natural and cultural resource that must be preserved.

The public comment period on the reviews of the national monuments continues until July 9th and Zinke’s recommendations to the president are due on August 24th. So far almost 370-thousand people have put in their two cents at regulations.gov.
