Here we are out on a lake in the middle of the forest that goes round from the south to the east of the airfield and not far from the building where the VHF receivers were kept.   As we were only about 8 feet above sea level the underlying soil was sand and the water table sinks in the winter when the surface is frozen causing the ice to crack around the edge of the lake and collapse back into the water.   YoursTruly On Ice.   This is me trying to maintain equilibrium.   The lake must have formed at the bottom of a quarry as you can see that the sides are about 20 feet high and we are probably below sea level here! - Feb54.   Subsequent photographs show that this was the assault course. Thanks to Google Earth, Dick and the Web Master have been trying to identify the lakes in the woods.   The bottom shot is a blowup of the lakes on the edge of the woods today and in both lakes the sloping sides can be seen.   Anyone else have any ideas? The position of the frozen lake is niggling Dick because he didn't think it was so far away from the camp boundary.   He had another look at Google Earth.   It slightly bothers him how we got out of the camp on the South side as there were only the crash gates (for which he bought a key from an ironmonger in Jever for 25 pf) and the ones you have marked would be quite a walk from the north side of the runway and make the return journey without missing a meal or getting caught in the dark.   Dick had further thoughts about the proximity of the 'lake' to the station and the restriction of the outer fence. He thinks the above suggestion is possible because of its proximity to the receiving station.   It could be the same place as the 'assault course' which would be dry or very shallow in summer time. Maurice Parker has come up with a most likely explanation.   He writes: "Dick seems to be on the right track in regard to where this small lake was.   A relation of mine was a GSO man and a GAF civilian dog handler and he tells me that there used to be a lake in the area were Dick has indicated on his map.   He also said that in 1961 when the RAF were preparing to hand over the station to the GAF, all surplus equipment was dumped here and the the lake was then filled in with earth.   This could then possibly account for the none existance today.   Dick must then be refering to the area he describes as possible frozen lake."   (Thanks to Dick Endecott and Maurice Parker)
