Other so-called rivers in Nevada are Quin River, a large creek which rises in Idaho and runs south in Humboldt County to a small terminal “sink” situated at the north end of a great range of mud flats and marshes that lie to the northward of Pyramid Lake. There are good stock ranges in the Quin River country. The Rio Virgin is a small stream about eighty miles in length situated in Lincoln County, in the extreme southeastern part of the State. It takes its rise in Utah and empties into the Colorado River. It has a tributary of considerable rise called Muddy Creek, or the “Big Muddy,” on and about which is much excellent land and several deserted Mormon villages. At one time there were 500 Mormon families settled in this part of Nevada, but they were called back to Salt Lake by Brigham Young, and abandoned their comfortable homes and fine and fertile farms. The mouth of the Rio Virgin is but 800 feet above the level of the sea, all this region being in what is known as the “Colorado Basin.” The climate is much the same as that of Los Angeles, California. Oranges, figs, lemons, almonds, olives, pomegranates, and all other semi-tropical fruits grow to perfection; also cotton and tobacco. All the grains, vegetables, and fruits of the temperate zone flourish finely. This spot is the Eden of the great basin region. The Colorado River forms the southeastern boundary of Nevada. Although it is not one of the rivers of the State system, yet it is one to which Nevada has some claim. Where it sweeps along the southern border of the State the stream is half a mile wide and has a depth of from ten to twenty feet. The river is navigable for steamboats from Callville, a short distance between the mouth of the Rio Virgin, to Port Isabel, on the Gulf of California, a distance of 600 miles. Callville is one of the towns (now almost deserted) founded by the Mormons during their occupation of that region of the country. The proposed railroad from Salt Lake City would cause this region to again become populous and prosperous. Mineral Treasures of Nevada.
