HistoryA character grade: shown, never part of Powell’s overall grade.
Wyoming towns list more on the Register than most of the country (a typical Wyoming town has 25.1 per 10,000 residents, the U.S. 2.4), so Powell’s 1.5 sits below most of its state (33% of Wyoming towns have fewer) while its 1 listings outnumber those of 51% of U.S. towns.

What stands out about Powell’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Powell was incorporated in 1909. Powell was named for John Wesley Powell, U.S. soldier, geologist and explorer. Powell post office was established January 23, 1908.
In 2013, the area was the subject of a piece of national legislation. The Powell Shooting Range Land Conveyance Act (S. 130; 113th Congress), which was passed by both the United States Senate and the United States House of Representatives, would transfer a piece of land from the Bureau of Land Management to the Powell Recreation District for continued use as a shooting range.
