Hi!!

I am speaking to a group next week about material in our Map Collection.

I was trying to verify some info that I thought I had read on this list ---

that there are 55, 000 --- 7.5 minute maps

and that USGS completed mapping the entire US at this scale in the last
5 to 7 years????

How far off is my memory??

Called USGS and they didn’t seem to have this info at their finger tips….

thought someone on the list might.

Thanks
