Gold was valued at $22.30 per ounce in 1876. $375,000 of gold would be 16,816 ounces of gold or 1,051 lbs. of gold. If 2 men hauled 40 lbs of gold a piece or 80 lbs. per trip that would be roughly 13 trips to the burial location.
This had become a very hostile area at the time. A real suicide mission to travel through that country. People weren't stupid back then.
The two variations that made the rounds in the treasure magazines of the "60's and "70's.The FAR WEST was employed to carry the wounded back to Fort Lincoln,the addition of the gold story was first mentioned by two treasure writers-Emile Schurmacher (The gold bars from Williston version) & Roy Norvill (The three miners version).
I do not know the source of their information.
As with many treasure legends,actual events,people,and locations have been added to provide a feel of veracity to a tale.
NOTE: March's account and newspaper accounts of that time never mentioned gold in the events of June 26,1876.
