Just west of Sun City, Sun City West, and The Grand rises the rugged skyline of the White Tank Mountains, home to White Tank Mountain Regional Park. While today it is known for scenic drives, desert trails, and spring wildflowers, its history stretches back thousands of years.

Long before modern development reached the West Valley, the mountains were home to the Hohokam people. Evidence of their presence remains in the form of petroglyphs etched into rock surfaces, especially in areas like Waterfall Canyon. These carvings offer a glimpse into daily life, beliefs, and survival in the Sonoran Desert centuries ago.

The name “White Tank” comes from natural rock basins that collect rainwater. Early settlers and travelers relied on these natural tanks as dependable water sources in an otherwise dry landscape. In the late 1800s and early 1900s, the area was used for ranching and small scale mining before eventually being preserved.

In 1961, Maricopa County established the regional park, making it one of the earliest large scale desert preserves in the county park system. Today, it protects nearly 30,000 acres of Sonoran Desert and remains one of the largest regional parks in the country.

For West Valley residents, the White Tanks are more than a scenic backdrop. They are a reminder that long before master planned communities and golf courses, this land supported ancient cultures, early settlers, and a very different way of life.
