I've seen things like this on the North Shore of Lake Superior where there
are waterfalls (dry at the time ;->).  I thought they might be caused
by water action swirling small stones around in the hole, making the
hole deeper and deeper.  These holes had straight sides, and were
usually about 3-4" in diameter and 9-12" deep.  Seems that someone
once told me that was where they came from, but I don't remember.
Oh yeah, they were so circular they looked drilled (but apparently
weren't -- at least there were no tool marks and they were too big
to have drilled for blasting).

As to their being on a mountain, remember that they may have been made
rather long ago.  BTW, there were usually a lot of these holes around
or none at all, but rarely an isolated one.
