New Delhi, March 25: Pamukkale, located in western Turkey, is a stunning destination filled with secrets. It is regarded as one of the world’s most unique and beautiful natural sites. Visitors flock here each year to witness its bright white travertine terraces and thermal pools.
From a distance, Pamukkale resembles a pile of cotton, earning it the nickname “Cotton Castle.” The white terraces and pools are formed by hot water from volcanic activity. Rainwater seeps through cracks in the ground, heating up from magma and dissolving minerals from limestone rocks. When this mineral-rich water reaches the surface, it solidifies, creating travertine formations.
Due to the accumulation of carbon dioxide from the hot springs, a cave in the area was believed to be the entrance to the underworld in ancient times, associated with Pluto, the god of the dead. Animals or humans entering this cave often met with a swift demise, leading to its ominous title, “Gateway to Hell.”
The water temperature in Pamukkale ranges from 19 to 57 degrees Celsius. Above these thermal pools lies the ancient Greco-Roman city of Hierapolis, established in the 2nd century BC and designated a UNESCO World Heritage Site in 1988. Nearby is Cleopatra’s Pool, where visitors can swim among ancient columns. A devastating earthquake in the 7th century caused significant damage to the city.
NASA’s Terra satellite captured images of Pamukkale on May 25, 2021, and October 9, 2021, using its ASTER sensor to study Earth’s surface temperature, glaciers, volcanoes, and environmental changes.
The accumulation of travertine in the Pamukkale region has been ongoing for at least 600,000 years, dating back to the Pleistocene epoch. However, most of the white formations we see today have developed in the last 50,000 years. Researchers believe the current arrangement of hot springs and travertine pools was established after the Laodicea earthquake in the 7th century, which altered the area’s geology and redirected the flow of hot water, accelerating travertine formation.
Over time, the temperature in this area has fluctuated. Hotter springs produce calcite travertine, while cooler temperatures lead to more porous tufa deposits. Geochemical analyses indicate that water temperatures have gradually decreased since the Pleistocene epoch.
