Lake, who continued to develop the community by adding a grist mill, kiln, and livery stable to the hotel and eating house. He renamed it "Lake's Crossing". Most of what is present-day western Nevada was formed as the Nevada Territory from part of Utah Territory in 1861. By January 1863, the Central Pacific Railroad (CPRR) had begun laying tracks east from Sacramento, California, eventually connecting with the Union Pacific Railroad at Promontory, Utah, to form the First transcontinental railroad. Lake deeded land to the CPRR in exchange for its promise to build a depot at Lake's Crossing. In 1864, Washoe County was consolidated with Roop County, and Lake's Crossing became the county's largest town. Lake had earned himself the title "founder of Reno". Once the railroad station was established, the town of Reno officially came into being on May 9, 1868. CPRR construction superintendent Charles Crocker named the community after Major General Jesse Lee Reno, a Union officer killed in the Civil War at the Battle of South Mountain. In 1871, Reno became the county seat of the newly expanded Washoe County, replacing the county seat in Washoe City. However, political power in Nevada remained with the mining communities, first Virginia City and later Tonopah and Goldfield. The extension of the Virginia and Truckee Railroad to Reno in 1872 provided a boost to the new city's economy. In the following decades, Reno continued to grow and prosper as a business and agricultural center and became the principal settlement on the transcontinental railroad between Sacramento and Salt Lake City. As the mining boom waned early in the 20th century, Nevada's centers of political and business activity shifted to the nonmining communities, especially Reno and Las Vegas. Nevada is still the third-largest gold producer in the world, after South Africa and Australia; the state yielded 6.9% of the world's supply in 2005 world gold production. The Reno Arch was erected on Virginia Street in 1926 to promote the upcoming Transcontinental Highways Exposition of 1927. The arch included the words "Nevada's Transcontinental Highways Exposition" and the dates of the exposition. After the exposition, the Reno City Council decided to keep the arch as a permanent downtown gateway, and Mayor E.E. Roberts asked the citizens of Reno to suggest a slogan for the arch. No acceptable slogan was received until a $100 prize was offered, and G.A. Burns of Sacramento was declared the winner
