7. The Topographic maps made by WPA surveyors were terrific for looking for archaeological sites, and

navigating your way through the outback of S. Florida. I guess it got to be a pain when there were so many new housing developments and roads, so the gov't contracted for new maps. The new maps seem to have been generated by computer from satellite photos. On one map there was a huge thumbprint covering half a "square". I don't remember what the square represents, but it covered miles and miles, obviously a thumbprint. Florida Everglades or Big Cypress area.
