Carsten Peter, Hang Son Doong, 2011

At a mammoth 2.5 miles long, 330ft wide and almost 800ft high, Hang Son Doong also known as Mountain River Cave, is as high as 25 double decker buses.

…Well, I guess someone found D’ni.  That was easy.

I’ve had several people submit various links/versions of Hang Son Doong over the past few days, so I’m just going to reblog it because it is still AMAZING.
