Lethbridge's next project focused on searching for a chalk hill figure that was reported to have once existed on Wandlebury Hill in the Gog Magog Hills, Cambridgeshire. Towards the end of 1954 he began investigating the site, inserting metal rods into the ground to determine where he believed the turf had once been removed to expose the chalk below. He believed that he had revealed three large figures, a warrior, a hooded goddess, and a sun god, asserting them to be likely 3000 years old, and then began excavation to remove the turf and reveal the figures. Lethbridge sought much publicity for his discovery, reporting on it to The Times and being interviewed by the London Evening News. However, many archaeologists were sceptical of Lethbridge's methodology and the existence of the hill figures; they believed that the soft patches of chalk were the result of chalk solifluction and were only interpreted as human-made figures through Lethbridge's vivid imagination. The Council for British Archaeology brought together a committee to assess Lethbridge's findings, composed of I. W. Cornwall, W. F. Grimes, Christopher Hawkes, and Stuart Piggott. With the aid of geologist F. E. Zeuner, the committee concluded that the shapes Lethbridge had discovered were natural, having been formed during the last Ice Age. However, Hawkes disagreed with his colleagues, and believed that while not proven, Lethbridge's conclusions could not be disproved. Lethbridge stuck by his original ideas, and wrote a book aimed at a general audience, Gogmagog - The Buried Gods on the basis of them. It was published by Routledge and Kegan Paul in 1957, but received no supportive reviews.
