The waterfall at Furnace, near Machynlleth, Wales.
I started by drawing with a white gell pen on the toned paper and then added gouache.
Sketched in a short dry spell between very, heavy rain. We were camping in a field and were fine but 3 or 4 fields away from us the grass was totally under water.
There is an interesting mid-18th century charcoal iron furnace next to the waterfall and sometimes you can the the waterwheel in operation.
