Lake Badarkhundaga, whose name means "begging bowl", is a glacial lake nestled in a corrie right under the Southern side of Mount Otgontenger. This freshwater lake is very deep, it stretches on 400 metres (1312,34 feet) long and 320 metres (1049,87 feet) wide. It's a sacred place that the locals regard as __Vajrapani's begging bowl.
Here, North from the sacred Mount Otgontenger, the official offering of the Mongolian State were presented to Vajrapani. Traditionally, offerings included a white horse with silver saddle and bridle, or a silver cup decorated with nine precious stones. After 1821, each year, silver, gold, corals, pearls and silver bars were offered to the lake.
