FLAGSTAFF, Ariz. -- Officials at Walnut Canyon National Monument are reconstructing a trail that gives visitors a view of 25 cliff dwelling rooms.
The one-mile Island Trail will be closed for the rest of the month.
Crews will be removing the asphalt along the trail to prepare it for repaving later this year.
Other improvements over the next two years include widening the trail, eliminating cracks and evening out the stairways.
The project won't impact access to another trail that runs along the canyon rim.
The monument east of Flagstaff contains ruins of dwellings built by the Sinagua Indians more than 700 years ago.
