(Okay, so I have a fertile imagination.)
Anyway, Brother Jumper's website explains it all: how he was taken away in the spirit and shown detailed maps of the hills in the area, how he held the brass plates of Laban in his hands (which I'm sure are as manly as his burning bosom) and how he was inspired to study topographical maps of the area and was rewarded with a sure knowledge of the location(s) of Book of Mormon events and of great discoveries soon to come.
In his own words: "How can I be so sure that this is the Hill despite all the dedicated research? For the same power of the Lord that hid these records up, were these records shown unto me, in a like manner that they were shown unto Joseph Smith Jr., and his witnesses. For I have seen the records and have been taken inside the cave at Cumorah in New York. I was given the opportunity while awake to hold the Brass Plates of Laban (Moses) in my hands and page through their leafs as I would a normal book, and I did feel the hieroglyphs thereon, which looked in the appearance of Egyptian, and before my eyes a phrase from the book of Isaiah was translated, and the phrase "A great and marvelous work is about to come forth unto the children of men..." was displayed before me.
Two times since have the plates been shown unto me, and from the mouth of that Nephite prophet who buried them up in Cumorah did he say "You shall testify that ye have seen these things, and that the time for their coming forth is soon at hand." And I Enoch Theos, servant and prophet of the most High God, even Jesus the Christ, testify that I have seen these things and that the Book of Mormon was indeed translated by the gift and power of God through his servant Joseph Smith Jr. and that again the Lord is rising up prophets for the final restoration of all things in this latter-day."
Personally, I often enjoy reading stories like Brother Jumpers's because they're so distinctly and peculiarly Mormon. He knows the location of the Hill Cumorah in the same way he knows Joseph Smith was a prophet. How can any Mormon apologist argue with that?
