A fur trader from 1878 to 1904, Schultz married a Pikuni (Blackfoot) woman, became a member of the tribe, and was given the Blackfoot name Apikuni. With the disappearance of the buffalo it was as difficult for Schultz to adjust to the new way of life as it was for the other Blackfeet. He took to the mountains and explored the eastern slope of the Rockies, hunting game and guiding other hunters and explorers, including George Bird Grinnell, the Baring brothers, and Ralph Pulitzer. He named mountains, glaciers, and lakes; he was the first to identify the mountain goat; and through his and Grinnell’s efforts the northern portion of the American Rockies was set apart as Glacier National Park.
