Good regional material, which fits into that market (Folkways series, Rivers of America, etc., curtailed in this instance by a somewhat limited interest in Idaho). Introductory highlights of geography, geology, flora, fauna and early history; then, in detail, successive chapters on phases of influence -- the Indians, the trappers, the explorers, the emigrant trains, the beginnings of colonization. To this aspect of development, due credit is given to the Mormons' genius for colonization. Too much-storied aspects of the Wild West are here, too -- lawlessness of the frontier, road agents, rustlers, outlaws, railroad camps and mining towns, discovery of gold, and Indian troubles as alien settlers disrupted the scene. Good picture of pioneer life. Final chapters deal with more recent history, with the development of agriculture, of cattle industry, of modern transportation, of local culture, education, religious background, and so on.
