you can go in find any quad in the USA, and print it for free. it will print each quad as a series of 5 pages, the 4 corners, and the contexual
map.
Not for Baja, but I wish I had this around for the past 25 years, probably would have saved me thousands (i'm a paper map guy)geoffff - 12-8-2019 at 05:51 PM
There's also CalTopo.
CalTopo has USA - and also Mexico & Canada. (I contributed the Mexico & Canada topos.)
Go to https://caltopo.com/map.html and click "7.5' Topo Maps" on the left. Then zoom in to where you want to go, and click "Print" on the top toolbar.

It was significant work on CalTopo's and my part manipulating the hodge-podge of free government maps (many thousands) into the web format you see
there.

Geoffff, I took a quick glance and noticed San Diego area map was from early to mid 70s but San Felipe area was this century.geoffff - 12-9-2019 at 12:41 PM
Yes, for the USA the decision was to go with the scanned paper topo maps - which are the older versions - because they include some useful historical
information which is sometimes missing/lost on the newer vector (digital only) versions. History seems more valuable in a topo map than updated modern
roads.
For Mexico, yes - it is mostly the newer vector (digital only) INEGI maps (with fallback to older scanned paper only when the newer map is missing).
We went this way because INEGI's paper map scans are mediocre quality
I will, at some point, also build an online map layer with only these older scanned INEGI maps.

Oh, and for Mexico, the maps will look much brighter with the hillshading layer turned off:

VERY nice, thanks. I'm impressed with the high quality, even when zoomed all the way in.
The older US format is fun to visit -- I see the railroad running along the coast in Manhattan Beach (it's been gone for decades).geoffff - 12-9-2019 at 01:19 PM
Yes, that's the advantage of the digital "vector" maps. They are super sharp.
You can see the difference here at Punta Santa Teresa where the digital map was missing from INEGI, so the old scanned map was substituted:
