Pima County officials are warning the public not to approach the site of a recent landslide in Tucson Mountain Park.

The landslide, which knocked down or destroyed numerous saguaro cacti, happened at about noon Sunday on the southeast side of Golden Gate Mountain. The area is not close to any roads or trails in the park.

“We’re asking that everybody keep a safe distance from the area,” said Karen Simms, division manager for Pima County Natural Resources, Parks and Recreation. “The ground is currently very unstable, and it’s going to take some time before it naturally heals.”

Several roads, trailheads, recreation areas and portions of the Chuck Huckelberry Loop are closed because of flooding, according to the Pima County Transportation Department. Recent storms have produced flash-flood warnings from the National Weather Service.

The Santa Catalina Mountain trailheads that will be closed are Finger Rock Trail, Pima Canyon Trail, Ventana Canyon Trail, Pontatoc Canyon Trail, and Bear Canyon Trail. All gates at these trailheads will be closed, and signs will be put up warning the public of the closure. 

County officials suggest not using the Loop through the weekend because of water, silt and mud. Loop closures are:

• All underpasses on the Rillito, Pantano and Julian
• Cañada del Oro Magee Road underpass
