Fire insurance maps drew every building, what it was made of and what it was used for, so insurers could price the risk of fire. Pick a year, then a sheet.
Euro-American settlement began in the early 1850s, and the population density remained very low until 1904 when the Southern Pacific Railroad built a switch yard and maintenance sheds there, after moving the division point from Wadsworth. In 1902, the Southern Pacific purchased a large tract of swamp-like land near its newly built railyard, and gave employees clear deed to a 50 ft × 140 ft (15 m × 43 m) lot for the sum of $1. It also offered to pick up and move every house in Wadsworth and reassemble it in this new town free of charge. As the population increased, a city was established, first called Harriman, after E. H. Harriman, president of the Southern Pacific, and then renamed Sparks, after John Sparks, then governor of Nevada.
