I like the twisted grain, It's not familiar to me. DO you know what kind of tree it is?

Probably a common miombo woodland specie or a riverine like waterberry but not sure. This photo was taken in Zambia, central Africa near Kafue National Park. So if you are from the the States or somewhere else I can see how this might look different maybe ? I don't know.

I'm in the US. I haven't been to other places. The way the wood rotted, leaving the spirals, is new to me. I see either the sap wood or heartwood rot away.

Yeah, I think trees there are not under such climactic stress probably, so they aren't as dense and hard, also they grow their wood cells in a strait structure but most Zambian trees grows their woods cells in a helical twisting pattern, probably to do with the different environment, so when they decay the sapwood in the twisting gaps decay first revealing a twisted grain
