북한산 스핑크스바위(Bukhansan Sphinx Rock)
Bukhansan Sphinx Rock is a rock just below Baegundae, the summit of Bukhansan Mountain. There are so many rocks that it is impossible to know the names of all these rocks.
I passed by here dozens of times and didn't know it was Sphinx Rock. It is difficult to know the name of a rock unless you study with interest.
