 <h2>Entrance series</h2>
 <p>From the entrance (roomy and dry enough to leave surface gear), take the larger, R stooping passage (L passage runs parallel to this and re-joins at the entrance pitch) to reach the entrance pitch series (RIG02 - see rigging guide). This starts as a short, sloping drop which lands at a bridge. From here a second short drop reaches 2 ledges in a much larger shaft. Below these ledges traverse out to the longest hang. <em><strong>This is always wet and responds rapidly to rain, quickly becoming unpleasant and it can be impassable.</strong></em> This drops down with a deviation to a large, loose, drippy ledge. Traverse out to the final short drop to reach a spacious chamber at the bottom of the entrance pitch series called <strong>Room With A View</strong>. (An emergency dump - bothy, stove, food, etc. - should be left here in case returning cavers find the entrance pitch series too wet to ascend).</p>

 <underground_description>The cave has a walk-in entrance, splitting just inside. The left passage comes out below a shaft from the surface, and apparently continues unexplored. The main passage reaches a 10m pitch, also below a surface shaft, which drops into a chamber. To the left is a short passage to an undescended pitch of about 10m, while to the right are three ways on. First is a rift, then a passage with an ice floor, and finally, half back towards the entrance, is a passage emerging below another surface shaft (passed on the surface just before reaching the entrance). This final passage also appeared to continue. Because a large carbide pig was found outside the entrance, it was assumed that someone else was in the course of exploring this cave.</underground_description><!-- Underground description.
