The story of the Lewis and Clark expedition is a well-known telling of the discovery and exploration of the American Western frontier. Renowned historian and author Stephen Ambrose depicts the trials and tribulations in his award-winning account of the journey westward, "Undaunted Courage." The telling of westward expansion after Lewis and Clark is one of success and adventure. However, the 100 years following the Lewis and Clark expedition include stories of hardship, failure, and relentless extremes. Many of these accounts are told in the writings of the men who endured these hardships, such as trapper Osborne Russel, trophy hunter and conservationist Theodore Roosevelt, and famous grizzly bear hunter and Missoula Montana resident William H. Wright.

This account of Western history touches on what sparked the migration West, from the demand for beaver pelts that kicked off the fur trapping boom during the early 1800s to the gold rush and livestock/predator wars of the 1850s. This is a brief overview of how the West was won (or so they say).

Cowboys and Indians: The West, not as expected

Hollywood depicts the western frontier as an untouched oasis of rangeland, forests, streams, and wildlife. Cowboys seen on the silver screen are fighting the American Indians from the Rio Grande to the Montana plains. The hard truth is by the time the Lewis and Clark expedition navigated its way across the plains to the Rocky Mountains, most of the pre-1492 American Indian civilizations were decreased by an estimated 80%. Settlements of Europeans on the eastern seaboard and Spanish explorers throughout the early 1500s introduced old-world diseases such as smallpox and diphtheria that spread through the native populations like wildfire and decimated their once large populations to a fraction of their original size.

Far fewer American Indian settlements were present during the Lewis and Clark expedition. The idea of the untouched West was met with the remnants of the American Indian encampments, agriculture, trail systems, and even the use of fire for habitat management. Many of the highways and interstate systems used today were built on a system of American Indian trails dating back to the eras before Christopher Columbus. These trail systems were established by the American Indians and mitigating wildlife, stagecoaches, the pony express, the first automobiles, and eventually modern-day transportation.
