644 Cave
Riaño 30T 0452084 4800220 Altitude 164m Length 6m

Updated October 29th 2002; 15th May 2006

An obvious 2m high entrance leads to 6m of passage which ends, too tight, with no draught. An alternative viewpoint, noted in summer 2002, is that the cave draughts out strongly and looks diggable.
The GPS reading, taken at Easter 2006, seems to place the hole rather a long way from the original coordinates (VP52150020).
