As discussed in the last blog, Nevada, created out of western Utah in 1861, had its eastern border moved from the 116th degree longitude to the 115th just two years later, taking that land from the Utah Territory. This was done to put newly found gold sites within the Nevada, which was closely controlled by the federal government, and at the same time take them away from the Mormons, against whom the government was strongly biased.
Nevada was on a roll in terms of increasing its domain, with the next expansion being towards the south. Brigham Young had seen the Colorado River as affording a possible route by which to bring in supplies and new recruits to Utah, so in 1864 he sent Anson Call to set up a settlement on the Colorado, which was done the following year, the town of Call’s Landing or Callville being located at the head of navigation on the river.
By 1866, the importance of this outlet for shipping was apparent to those in Nevada, so they petitioned Congress to give them the land which lay between their original border on the 37th parallel and the Colorado river. This, of course, was the western part of the Arizona territory, which complained the federal government about this land grab. However, because of its past support of the Confederacy, Congress didn’t like Arizona any better than Utah, and in January 1867 this 18,000 square mile section officially became attached to Nevada, which once again had benefited at the expense of a territory on Congress’s black list.
