    1. [GASCREVE] Topographic Maps, aka "Topos"
    2. Gee, Smith, you kind of threw me with that "dated" map comment. I never asked if they had "back" issues, I just order the "current" ones. Each map is "dated" and some of them are back in the 50's so its not like they issue new ones each year. And I would further doubt that they were even producing them in 1911. There ARE indeed maps of that era but NOT to my knowledge specifically produced by the U. S. Geological Survey in this common format for the whole U. S. I rather doubt that the U. S. Geological Survey was even in operation in 1911. This one looks to me for all the world like a WPA project that someone in government correctly figured actually served an on-going purpose so they kept it alive. Typically, stores that specialize in camping and hiking stuff will have a few topos on hand but they are usually ones that follow rivers or hiking areas or at any rate aren't particularly aimed at genealogists.....unless you just luck up on one. Usually they will order topos for you but they tack on a profit so its easier to do it yourself. Many years ago the USGS had an office in Atlanta where you could just buy topos over the counter but those days are long gone to the best of my knowledge. As you can imagine, these things don't exactly move like hotcakes so I speculate the government centralized the inventory for the whole country and you just order by mail. There may be an easier way to do it but my routine is to write: USGS - Information Services P. O. Box 25286, Mail Stop 306 Denver Federal Center Denver, Colorado 80225 Request information for ordering topographic surveys and tell them which state(s) you want. They will send you order forms and a huge, for example, map of Georgia that has the "quadranges" laid out over it so you will know which ones to order. There will be lists of other maps of possibile interest.....4 maps to make up all of Georgia for example, a map of the entire state, a map of each county, other specialized maps, etc. Typically its 3 or 4 bucks per map which you will consider a bargain when you get them. They are quite professional and, on the 7.5 minute scale you can do some serious pin-pointing. Contours are at 10' intervals. The "scale" you will likely want as a genealogist looking for (or plotting the coordinates for a known location of) cemeteries, churches, etc. is called "the 7.5 minute series", the 7 1/2 minutes being the "amount" of the coordinates east to west and north to south. In scale 1" equals 2000 feet. For example if you want to cover all of Screven County its about 8 or so maps. You may not want them all. They have names like Sylvania North Quadrange, Sylvania South Quadrangle, Hunter's Quadrangle, Brier Creek Landing Quadrangle, Jacksonboro Bridge Quadrangle, etc. And you order them just like that; i. e. specifying the names of the quadrangles. The "master" map with the quadrangles on it locates topographical features, roads, rivers, etc. so its not likely you will order more than you need if you have a fairly good fix on where you are looking. In a couple of weeks you should get the ordering material from Denver and then after you order its about another 3 to 4 weeks for delivery as I recall. I haven't done this drill in the last 3 or 4 years so if anyone knows if the procedure is changed please hop in and correct. Hope this helps you. John M. Poythress
