 <underground_description>The cave is basically four very close entrances in a line. A small crawl (First entrance) leads to an open pot in the middle of bunde (second entrance). The continuation at the far side of the pot is a second smaller open hole (third entrance) which is freeclimabable to a slope which leads to the first pot. At the top of the slope is a scary looking squeeze which emerges into an open slope (fourth entrance).</underground_description>
