Kongka La pass "underground base".

Kongka La is a high-altitude pass on the disputed Line of Actual Control between India's Ladakh region and Chinese-controlled Aksai Chin, where anecdotal stories claim UFOs are seen entering and exiting the ground, implying a hidden underground base. It matters as a modern Asian 'underground base' legend; the claims are purely anecdotal with no evidence, and the area's heavily militarized, sensitive border status makes independent verification effectively impossible.
