Location and accuracy The Robertson River begins at the terminus of the Robertson Glacier and flows northeast 33 miles to the Tanana River, 16 miles northwest of Tanacross. Because an exact location for the prospect is not known, the location is placed at about the middle of the river (north part of T. 18 N., R. 7. E.) and could be several if not many miles away from the location given here.
