Saturday, November 7th

    Day 7 of the field trip consisted of two main stops within the Lahontan Basin.   The first stop of the day  was Russell Spit, located approximately 14 miles south of Carson Lake within the Carson Sink.   Russell Spit is a classic example of a barrier spit and is probably one of the most well-known in the region. 

Locale of GPR Sites (77k)Accompanying our group was Dr. Ken Adams whose area of specialty is Lake Lahontan history and present day interpretation.  Our main goal for the day was to determine the relative age of the spit by using Ground Penetrating Radar (GPR) to find contact points between the spit and other surrounding features.

    Stop two of the day was within Adrian Valley.  Adrian Valley is located between the Pine Nut and Desert Mountain ranges.   It is thought that Adrian Valley is the remnant of a river bed formed when the Walker River redirected northward from its present course.  Our group used GPR to search for ancient stream channels that would have been left as the river dried out.
