Ashes are trees having compound leaves with (3 to 9) leaflets on opposite sides of a common stalk. Zimmerman (1969) indicates that the ash trees growing in the valley floors of our San Pedro River tributaries are of the velutina ("velvet") species, with leaves 4 to 6 " long and each leaflet 1-3" long and pointed at both ends. Leaflet edges are "wavy-toothed" toward the tip. Below left: young leaves on old bark; below right: leaves' velvety underside.
As of 2003, we have considerable numbers of young ash trees in Hot Springs Canyon above the Yellow Cliffs.
