Description 1



4.1. Guanyindong Cave

(length: 3,024 m; depth: -445 m)

The cave starts in an inconspicuous entrance portal (10 × 4 m large) at the bottom of an elongated doline densely covered by vegetation. Gently descending and meandering passage with stream and small steps continues next approximately 300 meters. The stream has other tributaries. Then, a relatively large cave space named Birds Hall (25 × 10 m) opens. Approximately 800 m behind the entrance, the passage continues via a 10 m deep step as a huge tunnel (up to 10 m wide and up to 30 m high). The upper part of the cave until the tunnel is named Old Guanyindong and the large following parts are named New Guanyindong. The tunnel has a flowing stream. The upstream part is ascends steeply and after ca. 100 m collapses to the surface occur. Downstream, the tunnel continues approximately 500 m but its height is decreasing (except two larger spaces) and after next several hundred meters (1.5 km from the cross with the Old Guanyindong part), the cave finishes in an impassably narrow space. Chert layers exposed from the limestone are typical feature of this cave.
