The newspaper archives are full of reports about giant skeletons being found. However, the reports always end the same way: The Smithsonian gets the bones and they are never seen again. If anything, they are dismissed as frauds or are lost and no records can be found of them.
This particular finding is unique because of the supposed large gun that was found with the remains.
The report is from 1910.
Giant Skeleton Found
Unmoved, unseen and untouched for hundreds of years, or so long a period that it can only be estimated by historians, and hidden in the recesses of a deep cave 25 miles north Shoshone, Lincoln county, in southern Idaho, states a recent Boise report. The place has seldom been visited and is known to but a few, is the skeleton of a giant ten feet tall, evidently of prehistoric origin.
As corroborate proof they are now exhibiting the rusty and timeworn barrel of what appears to be an old and ancient make rifle or gun weighing between 25 and 30 pounds, resembling a flint lock rifle, and which they claim was picked up besides the skeleton.
The bones will be taken out of the cave at the earliest possible date and carefully packed and forwarded to the Smithsonian Institute.
Its appearance, it is believed by those who have seen the skeleton, will result in an invasion of the caves in that section of Idaho by students wishing to see knowledge of the earlier inhabitants of America.
The skull of this giant is twice as large as that of the average man. The shape would indicate that the giant had a massive head upon his broad shoulders and the large limb bones indicate the giant must have been a man of great strength and physical power.
The skeleton is very well preserved and was found far back in the chambers of the cave stretched at full length. Close by was the barrel of the rusty gun, which is of make unknown to those familiar with firearms and considered a genuine trophy by its possessors.
No reasonable theory can be advanced by the discoverers as to how the skeleton happened to be in the cave. Those who have looked into the facts believe that the skeleton represents one of a lost race probably unknown to historians in this day and age, which occupied the American continent long before the red skin held the country in his power.
