- Need a legend.
Main Question or Discussion Point
I went to the usgs site and found the pdf, but for some reason I could not enlarge the file to read it. Any body got a link to the map with a legend? TIA.
That's the one, thanks.Is this the map you seek?
I downloaded the big version (712 MB).

It's all legible at high mag.
There is a bunch of text at the download site, and more text here, which lead me to the download site.
I went to another site first, but it didn't work.
