Old pencil drawings from my sketchbook

Here are some old drawings I had found in my sketchbook.  The first one is somewhere in the mountains above Los Angeles. I must have done it about 25 years ago! I think my original plan was to re-do it in pastel.

A little more recently, 2007, is a sketch of American Canyon Falls, outside of Cool, CA. I guess I was wrong in my Black Hole of Calcutta Falls blog entry when I said I had never drawn a waterfall before...
