Cloudspire

Cloudspire was the tallest mountain on all of Toril. It was located in the central Yehimal Mountains of western Kara-Tur, south of the Kun-Yen Shan range.

Geography
Cloudspire was located in the central highlands of the Yehimal, just to the west of the immense glacier on which sat the spelljamming port known as the Dock. It was south of the Kun-Yen Shan, north-west of the Po Yul Dzayul Range, and west of M'tsin Gompa in Tabot.

The mountain had little mineral wealth and several interior caverns, which were once home to dragons but were later the lair of remorhaz.

The mountain's precise height was unknown, but it was estimated at between 35,000 and 36,000 feet (10,700 to 10,900 meters).

Etymology
The mountain was known by many names to various species. The elves called it Arthael, whilst the dwarves referred to it as Yauvdagh. The gnomes called it Yavalaur. Human names for the mountain included Dzayur, Mount Huul, and Kulmont.
