Lava Butte is not a volcano although it reminds us of one. It is composed of volcanic rock called dacite, which has been dated at about 13 million years; so these rocks are very much younger than the Paleozoic sedimentary rocks of Frenchman Mountain. On a fresh broken surface, the dacite of Lava Butte is quite attractive. It is light gray to lavender and contains visible crystals of mica, feldspar, and hornblende. The conspicuous dark coloration is rock varnish, a superficial coating of clay and manganese and iron oxides.

Still working on a nice new descent route, we headed for the opening between the two rising white hills in front of us. Down this rocky wash and we were junctioning with a secondary main wash right at a short concave rock wall. Turn right!
