Odd Stratigraphic Names

The USGS has a great website for searching stratigraphic names and I've found some names that are a little different. I've listed some of the most interesting ones below. Note that many of these are from the western states, and there's a reason for that. Names of lithostratigraphic units (groups, formations, members, and beds) must named after a geographic locality, such as a county, town, river, or mountain, per the nomenclatorial rules set forth in the North American Stratigraphic Code. Many of the geographic localities in the eastern US are more puritanical, if you will, from early European settlers, while the western states settled in the mid- to late-nineteenth century were named more loosely. Also, note that not all of these names are currently in use, some of these names may have been abandoned in favor of another name(s) and others may have been proposed, but not formally accepted for one reason or another (e.g. it must have sufficient reason for naming the unit, it must be named after a geographic locality).

On a related note, I was once told a story by Dr. Doy Zachry about a grad student who was studying a sandstone bed that is informally known as the "middle Bloyd sandstone", currently being considered to be formally named the "Parthenon Sandstone" by the Arkansas Geological Survey. The student did a measured section of this sandstone near the community of Limestone, Arkansas, and saw the opportunity for a fantastic, but confusing, name. He said to Dr. Zachry that they ought to propose the name "Limestone Sandstone" for this unit. However, Dr. Zachry had to shoot down that suggestion for the obvious reason.
