In a switch from photography, this week's "park photo" is a sketch Kathleen Heideman drew at Badlands National Park. Ms. Heideman just completed a stint as artist-in-residence in Badlands, where she both sketched and photographed the landscape, as well as wrote poetry.

You can find this sketch, and others, at her flickr page. This is what she had to say about this sketch:

As I sketch, my "upper midwestern" aesthetic sensibility is frequently wincing, or crying (silently): "no! ack! don't use rose madder!! no cadmium yellow!!" – the palette of light here is certainly a shift from "Upper Michigan Winter." But it is fun to silence that inner color-cringing critic, and dip my brush in the vivid end of the spectrum for a change.
