In an undated report believed to deal with the selection of a site for the HFDF installation, The intercept station was located on a series of lightly wooded hills and rises about three miles from Adelaide River center. Adjacent to the station was a large clay pan some miles in area, which had been used as an emergency landing strip during 1942 but was abandoned since it could only be used during the dry season. During the wet season, it would flood to a depth of a few inches with the unflooded area turning into wet clay while in the dry season, the surface turned to a powder dry surface soil of low conductivity. However, even in the dry season, water could always be found a few feet beneath the surface. It was decided that this particular clay pan would serve well as an HFDF site; particularly since this and other clay pans in the area were about the only flat areas of sufficient size.
