We have found a couple of academic papers on the geology of the area which describes lakes formed in the Littleborough, Rochdale and Whitworth areas by the glacial meltwaters, what must the area have looked like then? – we think it’s too wet with rain now! They will be available for download from the website, http://skylightcircusarts.com/news/rochdale-fossils.
