The Stream Inlet of Ibbeth Perril Cave

This was taken in a high inlet in Ibbeth Perril Pot in Dentdale, North Yorkshire. The lighting really reveals the amazing shape of the passage. The shape was created by water disolving the rock along the fault in the Limestone. When the water table dropped the water was left trickling along the bottom of the passage and eroded the channels you can see in the floor.

Olympus OM1 with a 28mm wide angle lens. The shutter was left open and the caver fired the handheld flashgun in complete darkness. Original on colour negative film.
