Topographic Maps

USGS topographic maps of San Diego County, some nearby counties and the Lake Tahoe area have been downloaded from public-domain sources, cleaned up and posted here:

These maps are also available on CD-ROM. Just E-mail the webmaster at pje@efgh.com and provide a mailing address in the United States. The CD-ROMs will be mailed to you.

A few topographic maps of the area in and around Jeannette, Pennsylvania (where I lived many years ago) have also been posted here:

Many of the topographic maps are hard to use because they don't show major highways built after they were last updated. I have modified a few of them by overlaying some of the newer streets and highways. The results have been posted here:
