SB 8.2.1
sri-suka uvaca
asid girivaro rajams
trikuta iti visrutah
ksirodenavrtah sriman
yojanayutam ucchritah
Translation by His Divine Grace A. C. Bhaktivedanta Swami Srila Prabhupada:
Sukadeva Gosvami said: My dear King, there is a very large mountain called Trikuta. It is ten thousand yojanas [eighty thousand miles] high. Being surrounded by the Ocean of Milk, it is very beautifully situated.
