About World’s Tallest Thermometer
The World’s Tallest Thermometer stands in Baker, California, a small desert community located along Interstate 15 between Southern California and Las Vegas. At 134 feet tall, the structure dominates the surrounding landscape and serves as one of the most recognizable roadside attractions in the Mojave Desert.
The thermometer was constructed in 1991 by entrepreneur Willis Herron as part of the Bun Boy restaurant and gift shop complex. The structure was designed to commemorate the record-setting temperature of 134 degrees Fahrenheit recorded at nearby Death Valley on July 10, 1913. At the time, this reading was recognized as the highest air temperature ever recorded on Earth, making the height of the thermometer a direct tribute to that historic measurement.
Built with a steel framework and illuminated temperature display, the giant thermometer functions as both a monument and a working sign. The digital display can show current temperatures, often reaching triple digits during the intense desert summers that characterize the region. Travelers approaching Baker can spot the structure from miles away, making it a natural stopping point along one of the busiest highway corridors in the American Southwest.
The attraction quickly became a roadside icon, embodying the tradition of oversized novelty structures that flourished during the automobile age. Much like giant dinosaurs, oversized bottles, and towering statues found elsewhere across the country, the thermometer was designed to capture attention and encourage travelers to stop.
The landmark has faced challenges over the years. Economic difficulties led to periods of closure, and the structure required significant maintenance to keep its lighting and display operational. In 2012, the thermometer underwent restoration efforts that helped preserve the attraction and return it to working condition.
Today, the World’s Tallest Thermometer remains one of California’s most photographed roadside landmarks. Visitors often stop for photos beneath the towering structure, especially during the summer months when temperatures climb into the extreme ranges that inspired its creation. Whether viewed as a monument to meteorological history or simply as an impressive piece of roadside engineering, the giant thermometer continues to be a memorable stop in the California desert.
