Anyone know what caused these holes in rocks near McCall, ID? Specifically they were found on a hike from Boulder Reservior to Boulder Lake about 5 miles east of McCall.

I have seen holes like these on canyon walls, rock formations next to a trail, and even on creek beds. If the explosive is not pushed all the way into the hole, what's left behind is a hole that doesn't go through the rock.

So far that seems most believable-- except it is odd that one is in a boulder with rounded edges...
