The proposal was crafted specifically to avoid disputes that might arise from existing settlements of Euro-Americans. At the time of its proposal, the existing population of the Deseret area, including Southern California, was sparse, since most of the California settlement had been in the northern gold rush areas not included in the provisional state. Likewise, the border with New Mexico did not reach the Rio Grande, in order to avoid becoming entangled in the existing disputes of the western border of Texas. Deseret also avoided encroaching on the fertile Willamette Valley of Oregon, which had been heavily traveled and settled since the 1840s.
