Bladderpod wildflowers cover a hillside near Saddle Mountain

Introduction

About 40 miles (65 km.) west of Phoenix to the south of Interstate 10 at Tonopah are a pair of volcanic mountains linked by a saddle of lower hills. The more dramatic western peak is Saddle Mountain. It is composed of lighter-colored lava, tuff and rhyolite. The eastern peaks are nearly black basaltic lava of Quaternary Age. The Bureau of Land Management controls the major portions but there are a number of private holdings surrounding the mountains and there are quite a few mining claims (none of which appear to be active). There are nonetheless many entryways and easy hiking. As the Tonopah area grows this will be an important asset for recreation.

The most direct access is from Exit #94 off I-10, turning south on 411th Ave. Saddle Mountain RV Park on the left offers civilized camping. Several miles south 411th Ave intersects the Buckeye-Salome Hwy. Drive west or east on this little used road to find a number of trails or jeep roads leading into the foothills.

A few summer thunderstorms pushed into the desert over the past few weeks. As a result some summer monsoon species were open. Twenty-two species in bloom were counted, the most unusual for the location was Aristolochia watsonii.

Carpets of gordon bladderpod and big patches of poppies, phacelia and lupine. Spectacular! Show should last through early April.
