This morning I went out in the darkness and raindrops, and made the above sketch of the full canal. But I have discovered that I am not yet done with Sunken Canal after all. The top image is a 12x9 pastel started last night, and completed tonight. When thinking of the Sunken Canal I thought of a beautiful piece of music I heard a couple years ago, Old and Lost Rivers by Tobias Picker. The canal is now found and risen, but I still remember the Sunken Canal.
