Lava Tube and Brittlebush Picture of the Week

Everywhere I look, the desert is yellow, and it’s as thick as a jungle out there. When Queen Anne and I run into town, the train tracks—only a block from the road—are hidden behind the dense foliage. I supposed this was predictable with the good rains we had this winter. We had a good crop of poppies this month along with purple lupine and orange mallow lining the highways.

Several plants give to the yellow with the first to bloom is the Brittlebush. Their soft yellow flowers look like small pale yellow daisies on stems rising from sage-green leaves. Unlike the poppies, their color isn’t vibrant, but they’re so pervasive that they’ll turn mountainsides yellow. They thrive in disturbed soil, like the highway shoulders.

Creosote bush adds a second note of yellow. The lowly creosote is like the lawn of the desert, except it grows 4-6 feet high. A couple of weeks ago, the field across from the park was Kelly green. The bush’s flower is small—almost like buds, and now that they’ve popped, the green has a golden tint.

The yellow crescendo comes when the Palo Verde bloom. Last week, Her Majesty and I ran down to our dentist at the border, and along the way, the trees were already blooming in the low-lands. The bloom moves through the desert like an opening curtain into the highlands. Today I see the trees in our park are beginning to show the tiny flowers. At their peak, the Palo Verde dot the mountainsides with yellow splotches. It’s then you realize that they’re growing everywhere. There’s a color symphony, and quail provide the background music with calls as they stake out their territory. It’s the best time to live in the Sonoran Desert.

When Fred and I were out taking photos in Black Canyon a couple of weeks ago, I saw lots of brittlebush growing in the lava rock cracks. Their soft yellow popped against the dark, almost black canyon walls. Since they screamed, “Spring,” I wanted to capture the contrast. Out of the several shots that I took, I liked this week’s image best.

In the shot that I call Lava Tube and Brittlebush, three plants were growing below a gaping void in the rocks. I believe it’s a tunnel that formed when the molten magma lost pressure then receded. It’s just like when you were little, and your older brother tortured you by pinning you to the floor then drooled over your face but sucked the spit back at the last moment. The threat was always worse than the spit. Oh! By the way, on your first desert visit, inevitably someone will tell you, “Don’t sick your hand into any place you can’t see.” The lava tube is an excellent example of what they mean. I tried to get Fred to see if he could find any rattlers in there, but he refused. He was no fun at all.

Oh, if you’re wondering how brittlebush got the name, here’s an example of how they look after a couple of weeks without water.

Black Canyon Rocks Picture of the Week

The Sonoran Desert is at its best in April, when spring drags everything back to life. The cactus bloom, mesquite trees put out new leaves, palo verde trees turn yellow, the animals are horny, and there are dead snakes all over the highway. Each year we don’t have to run the air conditioning or the heater for two months. We manage the house temperature by strategically opening or closing the windows during the day. But, along with the beauty and rebirth, we dread the coming heat with being stuck indoors and up to our eyeballs in power company debt. It’s like having sex and then a kid.

Arizona has always been hot—well, maybe except for the millions of years when it was a sea bed, but that was a fleeting moment. Not all the heat was from the weather. Our state is a hot spot for volcanic activity. We have over 600 sites of volcanic mountains, cinder cones, shield volcanoes, lava flows, and lava fields. Our two tallest mountains—Mt. Humphries in the San Francisco Peaks and Mt. Baldy in the White Mountains—are volcanoes that spewed ash, cinders, and pyroclastic flows at the same time (talk about dual exhaust). Not all the activity is ancient history. The most recent eruption was about a thousand years ago, and it’s not over yet. Geologists say there’s a 13% chance that another outbreak will happen in the next millennium.

As a photographer, all of these bumps, cracks, warts, and irregularities are what makes Arizona such a remarkable subject for pictures. I’m sure the millions of people who come and stand at the edge of our big ditch in the north would agree. So, what does all this have to do with my self-assigned Nothing project? I’m glad you asked.

As you travel north from the Nothing pass, Highway US 93 makes a downhill run to the bridges at Burro Creek, and on each side of the road is a small lava field that doesn’t have a name (according to my references). It must be ancient because it has enough vegetation that blends with the surrounding landscape. Along the flow’s southwest border, there is a spring and wash that carved a ravine through the lava bed called Black Canyon. It was this landmark that Fred and I set off to explore last week before getting distracted by George’s Camp—ooh, squirrel.

Black Canyon is easy to find from George’s because its mouth is next to the property—across the street if you will. Within a few steps, we began hiking up a wash that had cut through the dark basalt lava. As we continued, the walls grew higher, and big, water-polished basalt boulders littered the oatmeal colored sand. Their smooth surface contrasted with the rectangular blocks making up the canyon sides. Even though we walked in deep dry sand, it was clear that a lot of water must flow along the course. When wet, the dark gray boulders turn jet black which would be something to see, but since some of them were over my head, I’d prefer the higher ground.

For this week’s featured image, I wanted to show the artistically placed smooth boulders contrasting the canyon walls. And I wanted to show the layers of textures: sand, worn stone, and rough wall. I also like the smaller white quartz placed within the basalt arrangements. Although I wasn’t paying attention to it, the mesquite’s bright new spring foliage adds dramatic color to the otherwise monochrome scene. I named this image Black Canyon Rocks.
