Tree ring dating

Tamarisk stem cross-section cut 2.8 m below the ground surface showing how sediment deposition is dated using tree rings.  Following initial burial of 68 cm in 1969, ring-width decreased, vessel size increased, and annual transitions became less distinct. After a second burial by 41 cm in 1972, annual transitions became indistinguishable.
