Engraving showing a Native American miner climbing a ladder made from a tree trunk. Lake Superior, one of the Great Lakes, is on the border between the United States and Canada. The Native American population of the Americas was drastically reduced after the arrival of the Europeans due to war, disease, forced removal and relocation, and the destruction of traditional ways of life. Illustration from 'Information respecting the history, condition and prospects of the Indian tribes of the United States. Part 5' by Henry Rowe Schoolcraft (1793-1864), published in Philadelphia in 1855.
