Hiking the canyon of the  Rio Santa Fe, over our heads the stone-cribbed hairpin turns that carried Spanish wagons, Civil War soldiers and Model Ts up this section of the Camino Real. The eroding pale strata of the canyon walls were capped by tumbled, slightly columnar basalt.

At the cliffs’ feet the rio’s busy water looped and twinkled. It smelled chemical; it was runoff from Santa Fe’s sewage treatment plant, equal parts groundwater from Buckman Wells and bottled water from Fiji that had been filtered through wealthy Santa Feans. Winding down that river was, no doubt, a lot of cocaine.

In the sedge at the brink I nearly stepped on a bull snake. We left, abruptly, in opposite directions.
