VML Dating of Bedrock Cliffs and Hillslope Deposits in the Drylands of Western USA


 

Figure Caption:   Optical microstratigraphies in rock varnish from bedrock cliffs and hillslope deposits in the Yucca Mountains, southern Nevada. VML dating indicates that the sampled bedrock cliffs and hillslopes have remained stable for at least 24 - 39 ka (Data source: Stirling et al., 2010).

VML dating indicates that the sampled bedrock cliffs and hillslopes have remained stable for at least 39 - 60 ka (Data source: Stirling et al., 2010).


 

Figure Caption:   Optical microstratigraphies in rock varnish from bedrock cliffs and hillslope deposits in Amagosa near the town of Beatty, southern Nevada. VML dating indicates that the sampled bedrock cliffs have remained stable for at least 12.5 - 24 ka (Data source: Stirling et al., 2010). Note that a prehistoric projectile point was found on the gently tilted slope surfaces beneath the dated bedrock cliffs.
