Maps of England - London 6 inch

The London County Series was produced in 1935 using the Ordnance Survey topographic base map of 1919-1920. This is a colour printed series not typical of six inch mapping elsewhere in the UK during the Great Depression. Each main cell number of the layout is divided into four sheets - NW, NE, SW and SE. The actual geological field work was generally pre-1920; the details are given in the marginalia of the individual sheets. The sheet layout is the same as the 1:10,560 OS layout, but the numbering is not. The London Series was unusual in that it includes a large number of summary borehole records deleted from later editions. These abbreviated logs give thickness of strata in feet and refer to a control level within the borehole column at the top of the London Clay (L) and/or the Chalk (C). This unusual and foresightful approach anticipated changes in surface levels due to excavation or infilling. I have not observed it on any other map or logging record. The descriptive table below is briefer than others on this website, as the maps are more uniform and can be described collectively here. The sheets are 23.75" x 18" or occasionally 26.5" x 18" (long) and are flat, bright and in Very Good condition, except where noted. The margins of some maps were neatly folded at the map edge in order to match to adjacent sheets. Prices reflect condition and location.
