My late wife, Dr Trina MacGillivray, was a geomorphologist. She loved the Netherlands and the Dutch landscape, but more than once made astute comparisons with the scenery of other northern European countries. The Dutch landscape, if it has a fault, is too organised, too well arranged and too manicured. Woe betide the blade of grass that dare step out of line. Trina’s observations extended to Belgium. If travelling to Brussels by train, it is immediately obvious when you have crossed the border because the landscape relaxes. It is not unruly or untidy, but, unlike the Netherlands, it does not need to maintain a near-geometric precision. Trina liked her trips to Belgium, too.
These memories were revived on a recent bus ride from Leiden to Hoofddorp, near Amsterdam Schiphol International Airport. It was a grey, overcast day – the sort of dreary weather that the Netherlands does too well and too often. Even before we had left Leiden, the regular geometry of the town impressed itself on me. But then there was something in the central reservation that caught my eye – a cluster of irregularly rounded boulders of various lithologies (Fig. 1E, F). It occurred to me then that such clusters of boulders were not so unusual in the Dutch landscape, breaking up the geometry in unusual ways (Figs. 1 to 3), yet were undoubtedly man-made.
