Las Vegas Territory is the "Golden Triangle" located between Arizona and California border. Part of the Territory is the life supporting Mead Lake created by the erection of the Hoover Dam on the Colorado River. The water from the lake supports the life of the fast developing City of Las Vegas. The main transportation life line of the Las Vegas Territory is the Interstate No 15 which runs from the Canadian border all the way through Montana, Idaho and Utah to Las Vegas and down south west to San Diego and the Pacific Coast. Connected to Interstate No 15 is a whole network of roads leading to the Great Canyon in Arizona and Los Angeles in California. The main hub for all of that is Las Vegas, the most dynamically growing City in the USA.
