Surrounded by mountain ranges, Las Vegas sits in a basin at the bottom of the Mojave Desert. This unique geography has played a significant role in shaping the city's climate, economy, and development. The surrounding mountains, including the Spring Mountains to the west and the McCullough Range to the southeast, create a rain shadow effect that contributes to the city's arid desert climate. The Mojave Desert, which covers a vast area of approximately 50,000 square miles, is characterized by extreme heat during the summer months and mild winters. The basin in which Las Vegas is situated is approximately 180 meters above sea level, making it one of the lowest points in the Mojave Desert. This low elevation, combined with the surrounding mountains, creates a unique microclimate that is distinct from the rest of the desert. The city's location in the basin also makes it prone to flash flooding, which can occur when heavy rainfall in the surrounding mountains flows rapidly into the valley. Despite the challenges posed by its desert climate, Las Vegas has thrived as a major tourist destination and entertainment hub. The city's early development was facilitated by the construction of the Hoover Dam in the 1930s, which brought an influx of workers and infrastructure to the area. The subsequent growth of the gaming industry in the 1940s and 1950s cemented Las Vegas's reputation as a premier entertainment destination. Today, Las Vegas is a thriving metropolis with a diverse economy that includes tourism, hospitality, healthcare, and technology. The city is home to numerous world-class resorts, casinos, and entertainment venues.
