A mountain of bison skulls

Taken sometime in the 1870s, this massive hill of bison skulls is a horrific monument to the U.S. Army’s insane mission to wipe out the Indigenous people of the United States. At the time, it was believed that the country’s native people relied solely on bison for their food, clothing and shelter. The government sought to get rid of the Natives by getting rid of the bison.

To go about their plan the U.S. Army was given the go ahead to indiscriminatly take out bison. Entire herds were wiped out, bringing the numbers of bison down from 60 million to something like 300(!) by the end of the 1800s. Thanks to Congress, bison numbers have risen to 200,000 today.
