Hollow tree stump

Inside of hollowed out tree stump.

[Madeleine Pennock]

A very usual colouring within the decaying tree trunk. I wonder why it is green and blue? It looks almost abstract and might be stronger with a tighter crop taking off the right hand side, and then don't give away the source of your photograph in the title!

[Steve Joyce]

I think the colours may be from mineral seepage. I like the idea of treating it as abstract. I thought it looked a little like a skull.
