  Two horizontal entrances in close proximity.  This, western, entrance is a squeeze into a small rift which deepens the passage. A low crawl follows, initially over mud and then over stal.  A stal narrowing in the passage can be passed but after that, the passage becomes blocked by stal. (The other site is 4793)
