Castle Cliffs rock fall

A rock fall from the slope below Castle Cliffs caused boulders to tumble onto the Valley Loop Trail, with some landing at the bottom of the hill. The largest boulder, approximately 3 m3 in volume, came to rest against a wood and wire enclosure built in the summer of 2024 to temporarily house an abandoned fisher kit. The fisher had been returned to the wild by the time of the rock fall, so the enclosure was empty and only sustained minor damage on its north side. The boulder, as well as a few smaller rocks, came to rest within 15 meters of the Courthouse.
