This is a loosely drawn illustration of two hikers on the trail. It was drawn for the final page of a fact sheet and intended for text overlay. The text primarily indicates avenues of further study and next steps of the project.

Part of a series of small inset drawings, this is quite simply, an Elk. The backdrop is that of pinyon pine and Red Butte.

This is a small inset drawing of a truck traveling a haul road from a mine site.  It is a southwestern landscape, and depicts dust kicked from the road and becoming airborne over the surrounding vegetation and landscape.
