Thanks for the tip. I was able to load the Desert southwest map to my windows computer, and it does cover the area of interest.
For some reason, I had trouble downloading the map to my memory card for my etrex20, but the second time around it worked. It asked me to choose which rectangles I wanted to download. On my etrex it is easy to see where the rectangles end, as the detailed topo data disappears.
