Charles and Lynn drove us out to Joshua Tree for some bouldering. I drew this from the backseat. The lines are all woogly from the bumpy drive (Check out the visor above Chaz's head, in particular) but I sort of liked how it forced me to draw loosely.
The park itself was cold and breezy, but very cool to look at. This drawing does little to capture how huge and bulgy everything looks. You can see where Chuck Jones got his inspiration for the backgrounds of the Roadrunner cartoons.
