SHRIMP in the Owyhee?? Fire up the barbee mate!
Dear Dr. Froude et al.:I concur with Dr. Jerque. He refers to a plethora of field evidence that adds detail to the story presented in Ninad's work. I'd like to add that you may want to check out a paper from the Idaho State crowd of Beranek, Link, and Fanning (see below). This paper came out some time back and offers a few possible numbers for ages of big picture events in the region. If I recall correctly, the most Owyhee-relevant discussion items are based on only a few data points compared to other drainages studied and could be strengthened by additional analyses. Nontheless, it is pretty darn interesting to this spud farmer trapped in the concrete jungle.
-SpudP.S. Dr. Jerque: I think we are on the same page about the Rytuba and Vander Meulen work. I did overstate its relevance in reference to the Now Voluminous (Once Dreaded) Rim Gravels but refer to it merely in the context that it provides evidence of a long-occurring interaction between volcanism, the fluvial system, and expansive sedimentation in the region. I wonder if it is even relevant to the latest question because "The inital influx of major fluvial systems into the volcanic field after about 14.5 Ma is reflected...."(see abstract)?
