A chilling soundscape

Imagine standing amidst the frigid air, bundled in layers upon layers of warm clothing, and hearing what seemed to be conversations from afar. According to the accounts of Snag’s residents, during this extraordinary cold spell, sound carried much farther and clearer than usual. Astonishingly, one could discern conversations from a distance of four miles, an incredible feat that was virtually unheard of during normal weather conditions.

Frozen breath becoming powder

Another intriguing phenomenon that baffled Snag’s inhabitants was the effect the extreme cold had on their breath. As they exhaled, their breath would transform into powdery particles before gracefully descending to the frozen ground. This ethereal transformation added an otherworldly quality to the already surreal winter landscape. For many, this strange occurrence only further emphasized the chilling power of Mother Nature in Snag.

The resounding booms of river ice

As if the experiences above were not enough, the inhabitants of Snag also witnessed the extraordinary booming sounds emanating from the frozen Yukon River. The snapping and cracking of the ice reverberated through the town, echoing like gunshots and creating an eerie soundscape that could easily send shivers down one’s spine.

Science behind the strange phenomena of Snag

The combination of low temperatures and changing air density played a crucial role in creating these mind-boggling phenomena. In extreme cold, the air becomes denser, allowing sound waves to travel much further and clearer than in regular weather conditions. As a result, conversations could be heard across long distances, giving Snag an almost paranormal aura. Similarly, the moisture in exhaled breath rapidly froze and crystallized due to the low temperatures, transforming it into a powder-like substance. Lastly, the intense cold put immense pressure and tension within the solidified river’s surface, causing it to crack and boom, generating sounds similar to gunshots.
