Not very often images can express the majesty or beauty of nature than these panoramas. It is a virtual tour recently featured by Google Doodles and it is very impressive! Its rare I click those but this was really worth it, mainly because it is not accessible to the public and special invitation only (scientific etc) to protect it. It is a bit off topic to my usual posts but this did require some serious tech and lighting to achieve these images! Great fun to Street View your way through the cave. I can only imagine how big this looked in person! My experience of caves apart from the Cornish coast as a child was the Nerja Caves in Spain where as a photographer for a magazine back in the day (80s) I had permission to use a tripod and medium format camera (a Bronica 6×45 with a wide angle tilt shift lens (very expensive lens back then!) with fujichrome slide film (long shutter speeds and people stood perfectly still so they didnt blur during the 5 second exposures! They still look amazing today in actual fact I have never seen a better photo of them so should maybe upload that to a picture library?
About
Sơn Đoòng is Vietnamese for “Mountain River”, an apt name for a gargantuan natural wonder. Inside is a fast-flowing subterranean river.
It is thought this cave was formed between two to five million years ago, but it wasn’t known about until a local farmer, Ho Khanh, stumbled across the entrance in 1990.
