BASALT RIDGE OVERLOOK

BASALT RIDGE OVERLOOK
Chunks of lichen-encrusted basalt litter the Basalt Ridge Trl.
Whether you’ve only skimmed its core trails or are a seasoned traveler of Scottsdale’s McDowell Sonoran Preserve, it’s easy to see that the 30,500-acre site is a wonderland of geological features.
Distinctive Cone Mtn. flanks the trails.
Brittlebush is plentiful along the route.
Upper Ranch Trail traverses the saddle of Brown's Mtn.
Invasive mistletoe attracts Phainopela birds.
In the preserve’s north sector, several popular routes wind among the impossible-to-miss mounds of Granite and Cholla Mountains that anchor a landscape of crystalized megaliths, nature-sculpted “mushroom rocks” and stony passages, while other trails wander off into areas with quieter dynamics.  As trail build-out progresses with in the North Valley preserve, more and more subdued places are being revealed.
Wolfberry shrubs thrive in moist areas.
Take for instance, the Basalt Ridge Trail.  Like most trails with the preserve, the short singletrack can be accessed via numerous connecting trails.  One scenic option is to start at the Brown’s Ranch Trailhead and take the Upper Ranch Trail. The beauty of this circuit is that it departs the heavily-travelled main corridor almost immediately.  The Upper Ranch Trail glides northward over the saddle between the pointed form of Cone Mountain and flat-topped Brown’s Mountain before descending into a sunny stretch of desert cut with sandy washes, arroyos and impressive vistas of the Cave Creek Mountains.  Where water settles in the drainage areas, fragrant patches of Triangle-leaf bursage, fruit-laden wolfberry shrubs, colorful masses of in-your-face brittlebush flowers and creamy Desert wishbone blooms put on lavish botanical displays.  Roughly 1.6 miles from the start, fist-sized globs of rust-and-ash-colored rock begin to appear scattered along the route.

Look closely and you’ll see the characteristic vesicular texture (holes formed by escaping gasses) of volcanic basalt. Unlike the showy, igneous granites that formed underground millions of years ago, this basalt is the result of surface lava flows or explosive events that also contributed to the site’s geological structure.  At the 1.8-mile point, the Basalt Ridge Trail veers off the Upper Ranch Trail tracing the crest of a low-slung rim.
Desert wishbone bush.
A half-mile and two junctions later, the Basalt Ridge Overlook spur leads to the nose of the rim perched above desert lowlands criss-crossed with dry washes and acres of mesquite.

From this tiny vantage point, views of the Four Peaks in Tonto National Forest to the east peek over Granite Mountain while the closer forms of Pinnacle Peak and Tom’s Thumb are visible to the south. Closer still are glimpses of the acres of preserve land set for future trail development that will undoubtedly add more surprises and deeper perspectives into this complex and beautiful terrain.
