Guys: On the issue of replicate names, here's a link to a USGS website where one can surf up the locations of a variety of names and then link to several map sources.
GNIS linkGo to domestic search on the left side for US stuff.
For instance one can overhear Silver Lake or Dead Indian Spring while sitting the barber chair, go home, and shake out exactly where it's located. Been quite handy for me
