The Rocky Mountains stretch from British Columbia to New Mexico and include more than 100 different ranges. Between many mountain ranges are rich river valleys. The Big Hole Valley, Bitterroot Valley, Gallatin Valley, Flathead Valley, and Paradise Valley have extensive agricultural resources. The parts of the Rockies in the US are divided into the Northern, Middle, and Southern Rockies with a separate section, the Wasatch Mountains, in Utah. The Southern and Middle sections are separated by the Wyoming Basin.
