Zane Grey 
U. P. Trail [EPUB ebook] 

From the master of the western comes a novel full of romance and adventure. The story begins: In the early sixties a trail led from the broad Missouri, swirling yellow and turgid between its green-groved borders, for miles and miles out upon the grassy Nebraska plains, turning westward over the undulating prairie, with its swales and billows and long, winding lines of cottonwoods, to a slow, vast heave of rising ground-Wyoming-where the herds of buffalo grazed and the wolf was lord and the campfire of the trapper sent up its curling blue smoke from beside some lonely stream; on and on over the barren lands of eternal monotony, all so gray and wide and solemn and silent under the endless sky; on, ever on, up to the bleak, black hills and into the waterless gullies and through the rocky gorges where the deer browsed and the savage lurked; then slowly rising to the pass between the great bold peaks, and across the windy uplands into Utah, with its verdant valleys, green as emeralds, and its haze-filled canons and wonderful wind-worn cliffs and walls, and its pale salt lakes, veiled in the shadows of stark and lofty rocks, dim, lilac-colored, austere, and isolated.
