rocky peaks, lofty and dangerous
崒 centers on a mountain that is dangerously steep and rocky, emphasizing a sense of towering, perilous height.
崒 combines 山 (mountain) with 卒, which likely contributes a sound element and may suggest abruptness or danger, fitting the idea of a steep, perilous peak.
A mountain (山) with a soldier (卒) standing on its peak: the soldier looks down at the rocky, dangerous cliffs below.
For シュツ, imagine a climber reaching the peak and shouting 'Shoot! That's steep!' as they see the dangerous drop: shoot -> シュツ.
