Tourist sites on the Navajo Nation, including the Four Corners Monument, will be closed through at least the rest of the year.

The Navajo Parks and Recreation Department cited a rise in coronavirus cases on the reservation and a tribal public health order in making the announcement. It said it will reassess in January.

The closure extends to rivers, trails, canyons and roads that lead to tribal parks at Lake Powell, the Little Colorado River, Antelope Canyon and Window Rock, for example.

The National Park Service separately oversees popular spots like Canyon de Chelly National Monument and the Hubbell Trading Post National Historic Site. But the agency said it will operate in line with the Navajo Nation’s orders.

The tribe reported 19 new cases of COVID-19 on Sunday and one death, bringing the total number of cases to 10,441 since the pandemic began and the number of deaths to 559.

A shelter-in-place order, mask mandate, daily curfews and weekend lockdowns remain in effect on the vast reservation that stretches into New Mexico, Utah and Arizona.
