lofty
崱 centers on towering height: a mountain that rises steeply and impressively, giving a sense of loftiness.
崱 combines 山 (mountain) with 則, which likely contributes the sound. The character is rare and its exact historical development is uncertain.
A mountain 山 towering over a rule-like base 則: imagine a peak so high it sets the standard for loftiness.
For ショク, picture a shockingly lofty mountain peak: shock -> ショク, and the mountain's height is stunning.
