Hermen Tsav is a spectacular canyon located about 400 km (250 miles) from the city of Dalanzadgad in the South Gobi Province. The canyon has a beautiful, large oasis about 6 km (3.7 miles) wide and 15 km (9 miles) long. The high cliffs (30 meters/100 feet) in the canyon were formed naturally from an inland sea bottom over 200 million years ago and contain fossilized remains of dinosaurs, turtles and crocodiles. Hermen Tsav is known for its stark beauty, but also for the full dinosaur skeleton found here in the past. Even now, one can sometimes see dinosaur bones and fossilized eggs on the ground.
