Yana caves near Gokarna declared geo heritage site by GSI

Karwar : In a significant move towards conservation of geological heritage, the Geological Survey of India has declared the Yana caves near Gokarna as a geo heritage site of national importance. The announcement was officially made through a letter issued on April 13 as part of the organisation’s 176th foundation day.

According to the communication, the rock formations at Yana Caves date back nearly 2,700 million years and belong to pre-Cambrian dolomitic limestone. Over millions of years, intense tropical weathering and chemical dissolution have led to the formation of unique karst features in the region.

The Yana area is said to host 61 distinct karst formations, making it one of the most geologically significant landscapes in the country. Among these, the towering Bhairaveshwara Shikhara and Mohini Shikhara stand out as massive black monolithic structures. These formations are not only geological marvels but are also deeply associated with local mythology and pilgrimage traditions.

Experts have welcomed the declaration, stating that it will help protect the fragile ecosystem of the region. Indian Institute of Science environmental scientist M.D. Subhash Chandran described the move as commendable. He highlighted that the area represents a rare combination of geological monument and rich forest ecosystem.

He further pointed out that the region plays a crucial role in sustaining water flow to the Aghanashini river. Due to the presence of limestone-rich dolomite, the groundwater systems in the region are stable and long-lasting, contributing to ecological balance.

The scientist also suggested that authorities should consider creating a buffer zone around Yana and its surrounding areas to ensure long-term protection of biodiversity and water resources.

The Geological Survey of India acts as the nodal agency for identifying and preserving geo heritage sites across the country. Such sites are recognised for their scientific, educational, cultural and aesthetic value. The designation aims to promote conservation while also encouraging responsible tourism and awareness about India’s geological wealth.

With this recognition, Yana is expected to gain greater attention from researchers, tourists and conservationists, while also placing responsibility on authorities to ensure its protection for future generations.
