For science geeks, the United State Geological Survey (USGS) is a beloved and respected organization providing a source of thorough scientific research which delves into the subjects of geology, biology, geography, and water, among others.

The Internet Archive houses a collection of more than 50,000 of their United States maps which are given freely for use in outdoor recreation, scientific research, emergency response, or general interest.
