Finding an address on a map can be taken for granted in the age of GPS and smartphones. But centuries of forced relocation, disease and genocide have made it difficult to find where many Native American tribes once lived.

Aaron Carapella, a self-taught mapmaker in Warner, Okla., has pinpointed the locations and original names of hundreds of American Indian nations before their first contact with Europeans.

As a teenager, Carapella says he could never get his hands on a , depicting more than 600 tribes — many now forgotten and lost to history. Now, the 34-year-old designs and sells maps as large as 3 by 4 feet with the names of tribes hovering over land they once occupied.

"I think a lot of people get blown away by, 'Wow, there were a lot of tribes, and they covered the whole country!' You know, this is Indian land," says Carapella, who calls himself a "mixed-blood Cherokee" and lives in a ranch house within the jurisdiction of the Cherokee Nation.
