The name “Sniktau” refers to the pen name of Clear Creek Country journalist Edwin H. N. Patterson. Patterson lived during the 1860s, and was a close friend of the famous poet, Edgar Allan Poe. Patterson claimed to have received the nickname “Sniktau” from Native Americans.


Loveland is the highest mountain pass in the world that is regularly open during the snowy winter season. When the Eisenhower Tunnel, the highest vehicle tunnel in the world, opened in 1973, it allowed motorists on Interstate 70 to avoid crossing the Loveland Pass directly. Loveland Pass used to be the only pathway to Denver over the divide. Trucks that can’t pass through the tunnel continue to take US 6 across Loveland Pass.


The pass is named after William A.H. Loveland, a Golden resident during the late 19th century. The City of Loveland near Fort Collins, Colorado is also named after him. Loveland was a U.S. railroad entrepreneur and businessman. He was one of the founders of the Colorado Central Railroad and a prominent figure in the state’s early history. Being the president of the Colorado Central Railroad, Loveland was instrumental in the expansion of the railroad network into the mining communities of Colorado. For much of the 1870s, he waged a fierce struggle with Union Pacific investors for control of the Colorado Central. He also served as Lieutenant Governor of Colorado.
