This book is a thrilling Indian story written by a famous old-time frontiersman James Willard Schultz (1859 to 1947). Schultz was a noted author, explorer, Glacier National Park guide, fur trader and historian of the Blackfoot Indians. While operating a fur trading post at Carroll, Montana and living amongst the Pikuni tribe during the period 1880-82, he was given the name "Apikuni" by the Pikuni chief, Running Crane. Schultz is most noted for his prolific stories about Blackfoot life and his contributions to the naming of prominent features in Glacier National Park. Mr. Schultz is one of the last of the old-time frontiersmen, who was with a tribe of Blackfeet for years; and his books, into which he puts his rich store of memories of bygone days, have been called “the best of their kind ever written."

"The Dreadful River Cave," originally published in 1920, tells the story of a young, brave, Black Elk, and his exciting adventures centering about a mysterious cave behind a water-fall. Like Mr. Schultz's other books, this story deals with real live Indians, not book Indians, and has plenty of action and interesting Indian lore.
