Dave in Alaska Posted December 7, 2011 Share Posted December 7, 2011 where do people get maps of the formations in your area? I know a few areas but would like to expand my searches. Thanks, Dave Link to comment Share on other sites More sharing options...
Fossildude19 Posted December 7, 2011 Share Posted December 7, 2011 (edited) Generally speaking, I don't have any "Formation Maps", per se. I have a copy of a geologic bedrock map of my state. I was able to purchase a copy of it at my state D.E.P. store. Many states geologic maps can be found online. Google image search might help you there. I have researched the names of the formations that occur in my state, and read countless PDF files found online (Google searching for the formation names) about them. Some of the pdfs described where the formations may outcrop in different areas. Some of my research has led to clues about sites, some sites I've had to try to "Re-Find", using google earth, and clues from the pdf's as to where sites might be located. The usgs site is also a good source of information. Hope this is helpful.

Missourian Posted December 7, 2011 Share Posted December 7, 2011 Due to a lack of decent geologic maps of my area, I usually have to go with topo maps, stratigrapic charts, marker beds, and gut instinct. Yes, Google.... I've found quite a few geo maps here and there just entering different combinations of keywords (state, region, county, town, period, stratigraphic names, etc.). Context is critical.

cgodwin37 Posted December 7, 2011 Share Posted December 7, 2011 If you have an iPad or iPhone, Columbia University has an application called Earth Observer. It has state geological maps, and old 7.5' sheet geological maps for a number of states. Also more generalized geological maps. I've actually found it useful in my research. check it out. They may have one for other smart phones, but I don't know. Link to comment Share on other sites More sharing options...
cgodwin37 Posted December 7, 2011 Share Posted December 7, 2011 Also check with your local state survey. Link to comment Share on other sites More sharing options...
