Hidden Teesside

Two entrances to Jet workings are easily located next to a path alongside Bold Venture Gill. The workings extend perhaps 20m in a grid pattern.

The tunnels are large enough to stand upright in and have very few collapsed areas.

This second set of jet working located about 300m away are much more unstable, three holes surrounded by fencing have opened up. The floor inside is littered with collapses and it can only be a matter of time before they totally collapse.

This whole area of the woodland shows much evidence of collpases from jet workings just below the surface and many more must still exist.

A pair of pill boxes guard both side of Blacks Bridge between Marske and Redcar.

This level of defense is probably due to it being adjacent to the site of the Marske Aerodrome, now only referenced in road names such as Barnes Wallis Way.

Blink Bonny is apparently Norse for “nice view” and it certainly is (although not on the day I visited due to low cloud)

The drift was associated with the Ailesbury Mines to the north east, a collapsed drift can be seen in the hillside, with the tip in front now being home to a bench and viewpoint.

The are numerous other tips and collapses in the area at the same level as these working.
