Hohokam rock art at the South Mountain Preserve, Phoenix, Arizona.

This is not the most dramatic petroglyph panel on South Mountain, but it is still a little gem. On any rock, around any bend on any trail, you might find a few images, chipped and scraped into the rock varnish. They are ubiquitous but hidden – and a small reward for paying close attention to one’s surroundings. 

The air, which is always hot, has grown heavy and hazy over the past few days. Humidities in the desert are reaching more than 25%, and in the afternoon the horizons are clotted with nascent thunderclouds. Downdrafts stir up sand and dust, and the wind chokes and stings. The conditions are right for monsoon rains, but so far I haven’t seen a drop. 

This photo was taken just after sunrise in the South Mountain Preserve in Phoenix, Arizona.

Points.

We’re at the start of our first Phoenix heat wave of the season, with temperatures getting close to 110°F (43°C). Except for early morning walks I’m staying inside – and sharpening all of my blue pencils. I’ll be posting some new work in cool-palette colors in the next few days.
