The presence of marine fossils at Upshi Ridge is evidence of the time when this high-altitude region was submerged under the Tethys Sea, millions of years ago, before the uplift of the Himalayas. Fossils of ammonites, mollusks, and other marine creatures have been found here, dating back to the Mesozoic era. While the site has no human historical structures, its significance lies in its contribution to understanding the tectonic history and evolution of the Indian subcontinent.
