The Smitty S Caterpillar is an art installation in the Las Vegas Wash watershed of Nevada. It is an impressive sight, consisting of 75 steel pipes, painted green and blue, that rise up to 30 feet in height. The pipes are arranged in a wavy pattern, mimicking the movement of a caterpillar. The installation was created by artist Dennis Oppenheim in 1998 and is located near the intersection of East Carey Avenue and North Las Vegas Boulevard.

Visiting the Smitty S Caterpillar is a unique experience that combines art and nature. It is a popular destination for hikers, birdwatchers, and anyone interested in exploring the natural beauty of the Las Vegas Wash watershed. Visitors can explore the area on foot, following trails that wind through the surrounding desert landscape. Along the way, they may encounter various species of birds, lizards, and other wildlife. The Smitty S Caterpillar is also a great spot for photography enthusiasts, who can capture stunning images of the sculpture against the backdrop of the desert sky.
