Because the scale of impact along the Carson River is so large, natural detoxification will occur over the eons by subsequent sedimentation, dilution and diffusion. Man will have little or no effect to detoxifying the sediments along the Carson River because the job would prove insurmountable. The presence of toxic wastes will certainly be recorded in the accumulation of sediments at the river's termination at the Carson Sink. Future geologists 100,000 years from now will find a curious sand and clay layer rich in gold silver, mercury, arsenic and other elements which was derived from the Comstock. This layer will have a sharp basal contact and will defuse upwards into normal sedimentation sequences. Indeed, the Carson Sink is the ultimate tailings pond for the Comstock. Ironically this is also the site of an amazing population of both migrating and non-migrating water fowl.
