Note the Tucson Mountains Chaos geography

Known by some locals simply as “Brens,” UN 3,990 or “Bren’s Better,” is an interesting desert peak. The mountain is a primo example of what geologists call Tucson Mountain Chaos, a confusing jumble of rock types. My hiking partner, trained in geology, recognized an odd variety of rocks in a seemingly senseless pattern, and some follow-up research confirmed we were looking at the following: limestone, volcanic tuff, rhyolite, granite and schist. On the northwestern slope of “Bren’s Better,” a incongruent gray chunk of limestone seems to ooze mysteriously from the red rock making up most of the mountain. “Bren’s Better” and neighboring Tucson Mountains are some serious rock-nerd eye candy.

Leaving the maze of developed hiking trails in the Tucson Mountain Park for the summit of “Bren’s Better” is a delightful treat. Departing the broad highway of the Yetman Trail, the hiker can closely (but not too closely!) examine the tough desert plants that call this area home: Palo Verde, Cholla, Barrel Cactus, the might Saguaro and more. Sounds from the city of Tucson seem to melt away as you go deeper into the desert and higher on the mountain. Dynamite views from the summit include neighboring Tucson Mountain peaks, the Santa Catalinas and downtown Tucson.

Note: There are three highpoint candidates along the summit ridge of “Bren’s Better”: While the northern point seems higher, the summit register and cairn are planted on the southern point. My GPS seemed happiest someplace in between…be certain to visit all three highpoints during your visit!
