Came across this rather large standing stone a few days ago, below Mt. Kang-Zee-Bong, near Ildong.
My poles are set at 44", which together with my day pack will give an idea of the scale.
Interestingly, the gentle concave face on the right, shown full on in the top photo, looks as if it has calved off a larger block; but that is nowhere to be seen, having presumably weathered away. The total height of the stone has to be well over 20 ft.
I was surprised it has not been carved with Buddhist script, as remarkable stones here (in Korea) quite often are, but there is no temple close by. I think the main visitors are the deer, and the odd solo hiker...
