Pulled up against the sheer walls of Vishnu Schist that line the Inner Gorge, Stanton obtained this downstream view next to a riffle. A piece of driftwood with smaller twigs around it is lodged between boulders of Vishnu Schist (lower left), and the gnarled remains of a dead tree are visible on the schist cliff at top left.

More than a century later, both the driftwood and the dead tree, a catclaw, are in the same locations. A radiocarbon date on fine twigs on the dead catclaw indicates that it died several hundred years ago. A small new Utah agave grows in a crack below this dead tree. A new catclaw has become established at left center. Other shrubs visible include sweetbush, Mormon tea, and needlegrass.

Eighteen years after the first match, the driftwood and dead tree are still present. The catclaw has grown larger, as have many of the other shrubs visible in 1992, notably the Utah agave beneath the dead tree. New catclaw acacia are now present along with several other new shrubs, notably sweetbush and perennial grasses.
