Something that is often overlooked is the names on maps and how they can help the prospector to locate likely areas to hunt. A good example of this is the colorful and strange names the 49ers gave to towns, ravines, creeks, streams, hills, and mountains where they hunted for gold. Also some of these place names have been renamed several times over the years.
One area that I hunted, I had with me an old 1890s map, a 1950s 15-min. topo map, and a 1970s Forest Service map and this one ravine had a different name on each map. So when I am studying old maps I often ask whats with that name, could this be an overlooked gold lead ? Ron
