In mid-February, Nick and Ruth and Hobbs and Jack and David and I set out from Phoenix to visit the Cabeza Prieta National Wildlife Refuge. We left Route 8 in Tacna and headed south along a red dirt road that crosses an endless creosote flat.

After a sweet night under the stars, we decide to investigate the dunes to the east at the foot of the Mohawk Mountains. Not surprisingly, they were much taller than they looked from a distance.

Ruth, David, Hobbs and Jack take a break to enjoy the view.

At the very top of the highest dune was a single desert primrose.

We continued south past the Sierra Pinta to Christmas Pass, where we scrambled up cliffs of friable gray granite shot with veins of quartz.

This is one of the few approved campsites in the refuge, and it's a good one.

The pass provided the first thought-provoking 4WD terrain.

A few miles south of Christmas Pass, we arrived at Tule Well, an old ranch site where a handsome windmill still pumps water for a large storage tank.

Here we joined the infamous Camino del Diablo, where so many early explorers and fortune-seekers lost their lives. The Devil's Highway is the only route around the fierce Gran Desierto that stretches over 100 miles from the Pinacate Volcano Field to the Sea of Cortez. Our route took us just north of the Pinacate lava flow, and the flour-fine sand of the Pinta Playa made for extremely difficult driving.

In the middle of this harsh environment, we suddenly came upon a field of wildflowers – a lush garden of verbena, desert primrose and desert sunflowers.

We camped that night near Papago Well, huddling around a fragrant mesquite fire while the wind howled across the Agua Dulce Mountains.

The unusually overcast sky made for a very spectacular sunrise.

The hike up Kino Mountain will have to wait for better conditions, but we were thrilled by the tiny flowers we found in Growler Pass. We saw a grand total of four other cars (one of which was the border patrol) in two days.
