yes, i noticed a considerable amount of boulder fallout on the portal road going up, BUT alot less going down? what caused this winter phenonomon? Ours truley Richard Piotrowski throwing boulders over the edge to ? kill time? stay in shape? a man thing? watch the boulders crash and roll? clear the road for other nature lovers? we may never know, but it would have been fun to get a video! thanks richard you make my trips fun and create great stories to tell my grandchildren.
