The Book of the National Parks
“ Peak's eruption of a thousand cubic yards of lava in a few hours thrills us more than the Mississippi's erosion of an average foot of her vast valley in a hundred thousand years; yet the latter is enormously the greater. The explosion of Mount Katmai, the rise and fall of Kilauea's boiling lava, the playing of Yellowstone's monster geysers, the spectacle of Mazama's lake-filled crater, the steaming of the Cascade's myriad bubbling springs, all make strong appeal to the imagination. They carry home the realization of mysterious, overwhelming power. ”
