The toilet serves a remote weather station at Kara-Tyurek in the Altai Mountains and is is perched on a cliff 2,600 metres above sea level.
People have been using the precarious potty since 1939, in the region with a name which translates as Black Heart in South Altayan language.
A recent survey of unusual toilets around the world found the Altai privvy to be the number one most extreme toilet.
That is a great shot. Reminds me when a tree next door was blown over and we saw the whole root system as it brought up the yard with it. Just sights of nature you just don't expect to see.
