- I first learned of Jesse Day when looking into the history of Dayton, Washington. Dayton is the namesake of Jesse Day (sometimes written as Jesse N. Day and Jesse Newberry Day). At the time of writing this, I am sitting in a campground a few miles from Dayton.
- United States Geological Survey (Wikipedia)
The United States Geological Survey (USGS), founded as the Geological Survey, is an agency of the U.S. Department of the Interior whose work spans the disciplines of biology, geography, geology, and hydrology. The agency was founded on March 3, 1879, to study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The agency also makes maps of extraterrestrial planets and moons based on data from U.S. space probes.
