Came across what looked like a naturally triggered pair of slides on our way up the ridge to 10420 from the Guardsman Passs Road gate. Appears to have fractured on old/new snow interface in patches. Picutres below tried to show the main path at about ~100 ft wide and another spot slightly futher up the ridge ~30 ft wide, both spots 10-14 inches deap, ~38 degree slopes, near due-north facing. A couple other parties and one back country education class in the area all sticking to ridge lines and skiing low angle, wind sheltered snow.
