Located to the south of Sumthrang Village, on the way to Sumthrang by the foot path that comes from Ura Pema Lingp's Stone throne-stand is known as the Gor Gem. This place was named after a stone which has a small piece of stone inside the hole on a rock slab which locals call the Gor Gem (Gor-stone, Gem-key and lock), meaning the lock and key of stone. It was considered to be the key and lock to the world of the dwarfs known as tselo chupa because their lifespan is ten years.
