Yolyn Am
Ömnögovĭ
Yolyn Am, also known as Lammergeier Valley, is a deep and narrow gorge located in the Gurvan Saikhan Mountains of southern Mongolia, within the Gobi Gurvansaikhan National Park. Named after the Lammergeier vulture, which inhabits the area, the valley is notable for its unique deep ice field that can reach several meters thick by the end of winter and stretch for several kilometers. Historically, this ice field persisted year-round, although recent climate changes have led to its seasonal disappearance by September. The valley's harsh desert environment contrasts with this icy phenomenon, making it a rare natural feature. Yolyn Am is also a vital habitat for diverse wildlife including the Lammergeier, Himalayan and Cinereous vultures, Altai snowcock, wallcreeper, Mongolian finch, Argali sheep, Siberian ibex, snow leopard, and numerous pika, especially near the ice field. Its dramatic landscape, combined with rich biodiversity, makes Yolyn Am a unique destination for nature enthusiasts and bird watchers.
