The entire 2 million-acre Coronado National Forest will be closed beginning at noon Thursday because of extreme fire danger.
The closure includes the popular Sabino Canyon, north of Tucson, officials said today.
The only exception will be that the Catalina Highway to Summerhaven in the Catalina Mountains will remain open to residents, business operators and the public. But no stops may be made at pullouts, trails or other sites.
"We recognize the impact this closure will have," said forest supervisor Jim Upchurch. "But these are unprecedented fire conditions."
Darla Sidles, superintendent of Saguaro National Park, said all high-country trails and sites in the east district of the park will be closed. The west district will remain open, and the 8-mile loop drive on the east district will remain open.
