Geology: Regional Geology

The ISGS sometimes leads geologic field trips for the general public. Many of their guidebooks have been scanned and made available on their website.

The ISGS has developed an interactive mapping site that allows users to download geologic guidebooks for locations throughout Illinois. The guidebooks contain information about the field trip route and the geology, landscape, and mineral and fossil resources of the area described.

The Institute on Lake Superior Geology is a regional geological society that holds an annual meeting that includes field trips and presentations on the geology of the Lake Superior region. Their field trip guidebooks have been digitized and are available through a website developed and hosted by the Precambrian Research Center at the University of Minnesota Duluth.

Over 20 MGS guidebooks have been digitized and made available through the University of Minnesota's digital conservancy.

The Association of Missouri Geologists promotes the study of Missouri geology. Some of their field trip guidebooks are available online.

Several field trip guidebooks describing the geology of various places in Wisconsin have been digitized and made available on the WGNHS website.

This website, developed by the Wisconsin Geological and Natural History Survey, provides access to a digital collection of work done by the USGS Lake Superior Division from 1882-1922. It includes information about hand samples, thin sections, field notebooks and maps of the Division.

Geologic guidebooks contain descriptions of geological features along and information on the location of those features. As such, they are excellent resources for information about local geology. The Guidebook Database is an index to geologic field trip guidebooks covering all areas of North America, primarly published between 1940 and the late 1980s.

This is a collaborative site produced by the US Geological Survey and National Park Service. The site presents a non-technical introduction to geology and geologic concepts using the geology found in U.S. National Parks.

This website from the U.S. Geological Survey (USGS) provides information on the geology of the National Parks by park name, state and geologic province. It also provides links to information resources on geologic maps and concepts.
