Sam Clemens traveled from Carson to Lake Bigler (Tahoe) via an ambiguous route to an ambiguous location. Robert Stewart was provided me with a possible route to Glenbrook via either the Kings Canyon road or the Wagner's Clear Creek Road. David Antonucci has provided me with a kml file showing the Ash Canyon - Washoe Trail. I'm wondering if anyone else out there in Twain-L land has done any research and/or has an opinion on this issue.
