Recall visiting sometime back 20 years ago - all the claims of how large the relief sculpture is are somewhat misleading. While it may be that large, it is in direct reference to a large smooth round stone surface that dwarfs it to relative insignificance.
Being on the NORTHERN side of the mountain in the shade most (if not all) of the day makes it even less imposing. Rushmore, in comparison, is dominating with only the sky to frame much of the outline. On a sunny day, blazing near-white stone makes the effect more impressive.
I could see you typing but you didn’t say anything!! Rushmore sucks compared to Stone Mountain!!
The Stone Mountain carving is the largest in the world, bigger than Mt Rushmore. Your critical assessment is way off base.
