I'm sharing a couple of the sketches that were done in the class I recently taught at the North Cascades Institute: Autumn Palette: Flora and Fauna of the North Cascades. We had lots of fun using walnut ink, and other water-based media, including watercolor. Here are a hoary marmot and Townsend's chipmunk, two of my favorite North Cascades mammals. We had a beautiful specimen of the marmot on loan from North Cascades National Park, thanks to Katie Roloson's efforts. The walnut ink drawing is by Phoebe Bachleda, and the watercolor is by Jessi Loerch.
