From the Sub-Series:

This subseries contains over 300 maps, charts, and drawings relating to the projects in the earlier subseries. They were grouped by project as much as possible and segregated by size for storage purposes. The items range from hand-drawn maps to USGS quadrangles to highway maps. Often they contain a wealth of handwritten data. Three maps were added as part of the 2011 Longenbaugh accession.
