Reed pipes from Burial AV1 at Horseshoe Caves, a fragment of which was radiocarbon dated to 3530+/-30 cal. B.P. Several of the reeds have been incised with parallel marks (see item at left); those shown on the right are bound with buckskin cord. At the time the bundle was opened, the reeds also had buckskin thongs coming out from each end. TARL Archives.
