DEEP: Quadrangle Reports

 
Quadrangle Reports
 
Quadrangle Reports (QR) were published in 1951-1980 by the State Geological and Natural History Survey of Connecticut. The QR Publication Series was revived in 2012 with the publication of Hartford South as QR40.
 
For some areas, the QR maps are of a historic nature, as the mapping has been superseded by newer work. The accompanying text however, is rich with information uncommon in newer mapping. The Quadrangle Reports are full of observations and data compilations that are not available elsewhere.
 
Quadrangle Reports (with maps) are available as downloadable PDFs.  (Download the free Acrobat Reader).

Once opened, maps can be viewed at various scales, printed full size (100%) on a large format plotter, and an area of interest on the map can be sampled or printed on a regular size printer. The publication scale for most QRs is 1:24,000; some older maps were published at 1:31,680. Layers in certain maps may be turned on and off using Adobe software.
 
The Quadrangle Report maps are presented in color and are georeferenced, so can be accessible to the AVENZA PDF Maps navigation app on many portable devices.
