Under the hood of its unassuming land formations lies a captivating geographical construct that makes Peter Sinks a cradle of cold. It is a result of a natural depression due to water erosion in the limestone.
Its intriguing bowl-like shape is adept at trapping
and retaining cold air. This unique
trait leads to remarkable temperature plunges branding Peter Sinks as the home
of some of the "coldest temperatures in the U.S."
Registering these biting temperatures, however, presents both a practical and scientific challenge. The customary weather stations in the region house atmospheric standard instruments positioned around 1.5 to 2 meters above ground level.
This approach is insufficient here as the heavy, icy
air in Peter Sinks tends to be most concentrated at ground level. Consequently, conventional measurements can
often under-represent the sunk-in, ground-level frost.
In a creative bid to overcome this challenge, the local National Weather Service (NWS) installed a specialized thermometer within the sinkhole at ground level. This innovative solution effectively now captures the true latitude of Peter Sinks' winter temperature extremes.
