This is a panorama shot of a fantastic Tufa Cascade on the Kadisi River. The Kadisi is a tributary of the Blyde River, and is found within the grounds of the Forever Resorts Blyde River Canyon, where we stay regularly on our birding and wildlife safaris. My usual morning routine is to lead my clients on a nature and birding walk along the Kadisi Trail, a spectacular ramble which takes one past many Tufa formations. The stream is incredibly rich in Tufa formations, from small cascades to a three-meter high waterfall (I still need to photograph the waterfall properly, but that’s not really possible while with my clients0. On this occasion the clients had decided to sleep in, so I grabbed the opportunity to head down in the early morning to explore some areas I don’t normally get to. The day was cloudy, and the light not great, but the plus was that there weren’t any super bright spots contrasting with dark shadows, which is often the cawse when the sun filters down through the forest canopy. Most of my clients are unfamiliar with Tufa. I’m no geologist, but I did one right an article about it in my ‘Geo-Man’ series, which were published in a small newspaper a few years ago. The basics are that, due to specific water chemistry, flow rates and the interaction of plants – in this case the moss growing on the falls and cascades – calcium carbonate deposition occurs, resulting in a waterfall or cascade that actually grows outwards over time, rather than cutting backwards into the bed rock, as is the case with a normal river or stream. The volumes of Tufa on the Kadisi River are phenomenal, and one can see where the main channel has shifted over time, due to the deposits actually changing the course of the river. In fact, in places one can walk along the old stream bed, with the current river flowing some distance away. All in all it is a great morning walk and is always a highlight of our stay in the area.
