Yellowstone Has a 150-Year-Old Sonic Mystery—and Scientists Still Aren’t Sure What Causes It

Yellowstone National Park has a long history of mysterious, odd sounds that have been reported for over 150 years. These sounds, which range from the humming of bees to the sound of distant bells or metal cables, are most commonly heard in the mornings near the park's lakes. The earliest accounts date back to the late 19th century, with descriptions from engineers like Hiram M. Chittenden and Edwin Linton. Chittenden noted that the sounds were often fleeting and resembled the ringing of telegraph wires or the buzzing of insects. Forbes, a scientist, described the sounds as a "twisting sort of yow-yow vibration" that seemed to originate from nearby treetops.

The exact cause of these sounds remains unknown, and various theories have been proposed. One theory suggests that seismic activity could be responsible, while another proposes that atmospheric phenomena, such as horizontally moving whirlpools of air, might be the cause. Despite these theories, no definitive explanation has been established. The phenomenon is not unique to Yellowstone, as similar sounds have been reported around the world. The park's unique combination of geothermal activity, geysers, earthquakes, and hot springs adds to the mystery of the sounds. The article does not provide specific numbers or instruments used to measure the sounds, but it highlights the ongoing scientific interest in understanding the cause of these mysterious sounds.
