From the Tonawanda News:
For at least the next month, crews will be removing loose rocks, boulders and other items from the Niagara Gorge near the Gorge Discovery Center in Niagara Falls State Park.
A release issued Monday by the New York State Office of Parks, Recreation and Historic Preservation characterized the rock-scaling project as a process regularly done in the gorge to “protect those using the trails for recreational purposes” from being hit by falling debris.
