Evaluation by W Weller of SCAU revealed deep levels of made-ground comprising a high percentage of industrial slag and ash as well as sand, brick, stone and 20th century household waste. The results show that deep excavations had been conducted across most of the site prior to the construction of the football ground in the early 1950s. There was no indication of the projected route of Stane Street, sometimes postulated to cross the site, although the depth of disturbance would probably have removed any evidence if it had been present.
