Constance, Jane and I were at Cope Park on Friday morning and discovered a new waterfall. We were excited (and a bit puzzled, but noticed a culvert that was not new – so the Flume had not sprug a leak), and started painting and sketching.

  

Within 30 minutes the frothy waterfall had quite markedly diminished!
After we had started our pictures based on the nice movement down the
hill. 

This is a new plein aire phenomenon. We are used to changing weather, tides, and shadows – but to have a waterfall stop within half an hour????

Oh well.
