Apologies if this has been posted before, but I just came across the http://www.natgeomaps.com/trail-maps/pdf-quads&apos ;">National Geographic PDF Quad Sheet site. They've taken standard USGS quad sheets and cut them up into multi-page PDFs designed to be printed on 8-1/2"x11" paper. And they're free!
Seems pretty handy Jim and I don't recall ever seeing it. Thanks for sharing.

Duly noted and saved as a favorite. Thank you for sharing, Jim.
Nice!
They've updated my area as well.
That is nifty site, thanks for the info..........:clink:
Thanks! This will come in handy. For some projects I can probably use these as the key map. (Downloading the full size ones and inserting them into the drawing can be a pain)
While they may have a general purpose (such as a quick print and go), they are made up of simple 256x256 image tiles, no vectors and no GeoPDF information for coordinate transformation.
Some may prefer the USGS GeoPDF Quads (also free) at the National Map.

The National Map site is especially useful for the historic quads.
I had been getting quads from libremap.org (which doesn't work currently, not sure when it stopped), so this is a new source, also I was not aware that the national map site was available. I bought digital versions of all of the 100K and 250K maps years ago, but the 24K were available free, so I just download those when needed.
Thanks for those links. Quad maps are, to me, a work of art. In the pre-digital days I used to collect them, I probably have near a thousand, including a lot of foreign ones. I would always try to get some local topos whenever I go overseas.

Hope this isn't to off subject but they often brag around here about our mapping abilities and history. http://152.87.4.98/heritage/maps/index.htm

definitely TVA was instrumental in developing photogrammetric mapping. I just watched a movie over the weekend...Wild River

Took a quick look at a couple of maps. What seemed to be missing was the notation as to the year of last update. This really leaped out when looking at one case where part of a large lake is on one map and part is on another. One map showed the lake as existing. The other was still showing pre-lake conditions.
