This page gives the names of the 31 USGS 7.5' Topo Maps that cover the SGM, along with their publication dates. The latest publication dates have been taken from the USGS Mapfinder Topo Map Coverage of the SGM page. However, the latest dates given on that page do not appear to be correct!
That page claims that six new maps were released in 1999, so I ordered four of them. The dates on the maps I received on 3/11/00 were all 1995, not 1999. Also, some dates listed in the Topo! CD-ROM for San Diego County are later than the dates given on the USGS page. Hence I conclude that those dates have some serious errors in them. I wrote them on 3/1/00, got a reply "we will check into this" on 3/3/00, but have not heard from them again as of 3/11/00. Hence until this is cleared up, don't believe any dates past 1995.
When available, I list some previous dates of publication collected from the maps I own. If you can supply additional publication dates from your collection, please let me know.
The USGS topo maps that cover the SGM are much more recent than other areas in Southern California, with all but two maps from 1995 or later. For comparison, the median year of maps covering the San Bernardino Mountain National Forest is 1988 (oldest map is 1958!), and is 1975 for San Diego County (oldest is 1959!).
Like me, you may find your entire collection of topo maps is out of date! The new 1995 maps that I received have significantly more information on them and are much easier to read.
All USGS topo maps are now available on the web at TopoZone, although they don't state what the dates of their maps are. For other maps on the web, including ordering topo maps, see Maps and Topographic Information.
