The summer rains, locally called the monsoons, are quite different from the widespread and gentle rains of winter. Summer rain events usually arrive in the form of violent thunderstorms, and can be highly localized. They can produce torrential downpours and flash floods over a relatively small area while other areas nearby remain parched. These small yet potent storm cells can deliver severe downpours with a focused intensity, leaving the perfectly dry neighbors to enjoy the visual spectacle. This one was a late summer storm just to the southwest of the J-Six Ranch area of Cochise County, Arizona.
Countless columns and spires of rock fill the landscape below Massai Point in Chiricahua National Monument, Arizona. The product of explosive volcanism, wind and water erosion, and eons of time, this area was dubbed “The Wonderland of Rocks” by the early settlers.
In the Arizona Upland portion of the Sonoran Desert, the plant that commands most of the attention is the iconic Saguaro with its tall stature and dramatic form. In moving from the desert valleys toward the surrounding higher terrain, the plant community becomes increasing dominated by grasses and presents a decidedly low stature aspect. There is one plant, however, that towers over its neighbors in these vast arid grasslands in much the same way as the Saguaro dominates the desert valleys. In southern Arizona that plant is the Soaptree Yucca (Yucca elata). Other species of Yucca replace it in other regions of the grasslands. They, like the Soaptree Yucca, can become quite massive and grow to a height of fifteen feet or more, and can be seen standing tall in the sweeping mid-elevation seas of grass.
A lone isolated storm moves across the desert, trailing a curtain of rain beneath. As luck would have it, this storm cell moved over part of the Mulberry Fire and aided firefighters in controlling its spread. From this vantage point, the showers seem to douse the sun, a fitting metaphor for its fortuitous appearance over the wildfire.
The Sonoran Desert of Arizona shares many of the same flora and fauna as the Chihuahuan Desert further to the east. Both deserts also share a similar climate and the same basin and range topography. Despite these similarities however, the Sonoran Desert presents a different visual aspect than its cousin to the east, largely because of the presence of taller stature plants. Towering Saguaros dominate the Sonoran Desert’s Arizona Upland to the extent that they become a feature of the landscape, but in addition, there is a profusion of small desert trees such as Palo Verde,Ironwood, and a number of others. This produces a striking contrast to the low stature vegetation which dominates the Chihuahuan Desert, and because of all its desert trees, the Sonoran Desert is sometimes called the arboreal desert.
