The entrance to site 3151 is in a walled enclosure and leads over debris into a hands-and-knees height chamber / passage. A row of stal down the centre leads to where the floor slopes up to a flat out crawl and possible continuation. There may also be a way off to the left. There is a slight outward draught.
