Throughout the nineteenth century, the American West was the destination of an astoundingly tremendous number of people: The east experienced an economic recession in 1837 that prompted many pioneers to head west, looking for better opportunities and a new life; gold was discovered in California in 1848, and when the rumor spread the following year, the "'49ers" flocked to the goldfields there, in what has been said to have been the largest human migration since the Crusades; then, after the Civil War ended in 1865, many disenfranchised Southerners decided to leave their devastated homelands and head in the same direction as the pioneers and prospectors before them.
It all began in earnest at the beginning of that century, after the Louisiana Purchase of 1803 and the subsequent Lewis and Clark expedition (1804-1806). This 'Corp of Discovery' was launched to assess and take inventory of this 828,800 square mile tract of United States land newly acquired from France, most of which had not been documented (and also to keep foreign interests such as England from intruding by establishing an American presence upon it). One of the major tasks assigned to them was to record and classify what would prove to be an amazing array of animals previously unknown to science, which then President Thomas Jefferson had a passionate interest in.
The later arrivals were arguably just as impressed by both the creatures themselves and their shear, incredible numbers; the bison herds were especially impressive in the latter sense.
Unfortunately, while the waves of newcomers were indeed awed by these animals, these very same people were actively and rapidly depopulating the wildlife. Many of these populations, such as the bison, beaver and wolf native american indian dog, have never entirely recovered.
Yet these new emigrants were not the only ones to blame for this devastatingly severe reduction in the numbers of these species. In fact, the Native American Indians became involved and were also actively participating in the devastation. Many of 'The People', as they have commonly called themselves, had become increasingly dependent upon trade goods and thus more indebted to the traders; the latter reacted by demanding more pelts and hides from the former, in exchange for debt relief and items the Natives couldn't manufacture themselves nor acquire elsewhere.
Most people usually think of the Great Plains horse culture when they think of the indigenous people of the West. Yet, there are other cultural regions in the American West, each with it's own unique customs, languages, cosmologies, stories, ceremonies, and spiritual practices. Furthermore, within each region is a variety of groups, whose diverse customs were and are similar, but not exactly the same.
In the traditional beliefs and world-views of The People, the animals all around them have been perceived as being spiritually potent, each creature possessing their own unique and individual powers.
