Here are some Topographical maps, and other kinds of maps, mostly for places I like to hike.
These are Portable Network Graphics (PNG), Portable Document Format (PDF), Jpeg 2000(jp2), or Jpeg (JPG) files
Yes, they are big files.

The ones starting with "o3..." are USGS 7.5 minute topos, downloaded from http://casil.ucdavis.edu/mapsurfer/ (The California Map Surfer), then usually I straighten them out (rotate, clean, etc). "f3"s are 1:100000 scale USGS TOPOs, and "c3"s are 1:250000 TOPOs.

The ones starting with "34" through "38" were once available from the forest service at http://svinetfc4.fs.fed.us/rastergateway/regions/r5/r5.html , but they dissapeared. http://svinetfc4.fs.fed.us/rastergateway/ is still alive. I have modified a lot of these to make the file sizes smaller, etc. The forest service maps are better, but unfortunately they don't include quads without National Forest land in them

There are a number of nice "GeoPDF" USGS TOPOs available in my USGS GeoPDF Maps folder - go there for details

http://www.geocommunicator.gov/GeoComm/index.shtm is great for locating old mines, BLM land boundaries, and lots of other stuff.

Get "Forest Visitor Maps" at http://www.fs.fed.us/r5/forestvisitormaps/ as PDFs by clicking on a map and then on "Printable Version", or just go to my National Forest Maps folder 

The Old30MinuteTopos folder has some old 20 minute and 1 degree maps. The name shows the scale, quad name, date and date reprinted.
