[1] The county was named for John Logan, a general during the American Civil War.

[3] One of the county's distinctive features is a mile-long stretch of Smoky Hill Chalk bluffs that tower 100 feet (30 m) high over the Smoky Hill River and are dubbed "Little Jerusalem" for resemblance to the ancient walled city.

In 2016, The Nature Conservancy purchased the property and the Little Jerusalem Badlands State Park opened to the public in October 2019.

[5] For many millennia, the Great Plains of North America was inhabited by nomadic Native Americans.

In 1803, most of the land for modern day Kansas was acquired by the United States from France as part of the 828,000 square mile Louisiana Purchase for 2.83 cents per acre.

Only two Democrats have ever carried the county in a Presidential election: Woodrow Wilson in 1916 and Franklin D. Roosevelt in 1932.

Since at least 1888 only three other Democrats have passed forty percent of the county's vote: Roosevelt in 1936, Lyndon Johnson in 1964 and Jimmy Carter in 1976.

In fact, apart from Michael Dukakis in 1988 during an election held during the grip of a major Plains drought, no Democrat since 1980 has passed 21 percent of the county's vote.
