"Selwyn was intensely interested in environmental and urban geology, and may have been one of the earliest environmental geologists in modem England. He eagerly sought out each new excavation and outcrop in the city of Leeds, meticulously describing its stratigraphy, structure, and palaeontology. He added immensely to the fund of knowledge of the Leeds region, and was commended by the Institute of Geological Sciences (specifically, by Dr. A. W. Woodland, August 30, 1967) for his meticulous, careful and outstanding work."

I remember his rushing off to new exposures when tipped off by Leeds City Council. No GPR of course.
