The mountain was known as "Moo Ak"  or "Moo Jin Ak" due to its location in Moo Jin Joo, the former name for Gwangju.
As most of the big mountain ranges are related to shamanism, it was also called "the Grave Mountain" or "the Shaman Mountain".
The Moodeungsan range is primally composed of soil rather than rocks.
It was called "Seo Seok" mountain during the Goryeo dynasty.
It was after the introduction to Buddhism in Korea that it was called "Moodeung san".
People believed the grand tower of the mountain cannot be compared to the mankind.
This is interpreted through understanding the roots of the name through Chinese "Hanja."
The name comes from Gwangju's original name, Moodeul or Moodol.
The "Jin" in Moojin is read through the Chinese roots in characters, but in the past, Deul or Dol is read through native roots in Korean.
Moo Deung is also similar transliteration.
There is also a placed called  "Soo Ip ee" so there are more circumstantial evidences.
