This map is very similar to source 69, but only covers 1/3 of it as 69 is a compilation of three different 100k maps. It also has separate surficial and bedrock layers.
While the geometries are very similar, they are if anything less detailed. However, the descriptions seem to be completely different. This might be a good example of deprecating an old map for a new version?
