----------------------------Original message---------------------------- map folks-- It occurred to me that this is quite the laziest-- and the quickest-- way for me to get this info... (I'll be putting it on the Geonet, too; sorry for the duplication). In putting together the poster for Boston, I thought it would be fun to update Kit Fuller's list of geologic map indexes (GIS Proc., v. 15, p. 85-89). Did a search on GeoRef and then on the USGS CD-ROM, but, because of the oddnesses of index terms, I'm not confident that I have them all. SO, could you zap me a list of the indexes to geologic mapping (published, open-filed, thesis, EVERY SOURCE) for your state. I'm only interested in current indexes, so if an index supersedes an older index, I only need to know about the current one. Thanks-- and we'll see you in Boston! -- Connie Manson [log in to unmask]
