Situated on the eastern side of the depression containing site 320, the 2 x 3m entrance leads straight to a sloping floor and climb down to a choked floor. At roof level the passage continues mainly walking-size for about 40m to a soft calcite choke with a small continuation beyond. The entrance has been marked CM1 with green paint.
