Lewis and Clark discover that wild hunted game can be too lean for use.
The Big Fat Surprise
"Even Lewis and Clark reported this problem during their travels in 1805: Clark returned from a hunting party with forty deer, three buffalo, and sixteen elk, but the haul was considered a disappointment because most of the game "were too lean for use." That meant plenty of muscle meat but not enough fat.
