It's unlikely there is an unknown burial site in the area around Grand Junction. Based on other CS burial locations from the time it was the habit to inter them in a local established cema[tary. An example is the old LaGrange Cematary located just north of Lagrange(Lagrange is located about 2 miles west of Grand Junction on the M&C line) which contains a number of unmarked CS wartime graves. I even came across a wartime mention of this in a letter home from a union officer stationed at Grand Junction. The federals seized the line of the M&C from Memphis to Corinth shortly after the fall of Memphis and garrisoned the towns along it for most of the war. Grand Junction was the district HQ.
