This one does have some large boulders out front and that's were we started the dig. We call them "knapping rocks" or "knapping stations". We're just about done with the digging around them. Most of the shelters around here have mature and immature trees just past the drip line which makes for difficult digging but I agree, sometimes there is much more out front. Next dig, I'll snap some pics of the front and post them up. Old topic but still a great lesson for those that haven't dug much or who have otherwise disregarded the front of a shelter.
