I've not published much corroboratory information about the Book of Mormon lately.
In doing some online searching, I found this wonderful Native American (Sun Cross) Solar Cross. Taken from the Spiro Mound Complex, the artifact indeed confirms Native Americans new about the about the Cross long before Cortez and Columbus sailed to the New World.

John 10:16 kjv
16 And other sheep I have, which are not of this fold: them also I must bring, and they shall hear my voice; and there shall be one fold, and one shepherd.
6 My sheep wandered through all the mountains, and upon every high hill: yea, my flock was scattered upon all the face of the earth, and none did search or seek after them.
11 For thus saith the Lord God; Behold, I, even I, will both search my sheep, and seek them out.
Engraved conch shell gorget with a "sun circle" design decoration. This specimen was first published by Brown and Hamilton (1965:Plate 4); Brown (1996:594, Figure 2-134j) illustrates this specimen as a type 3 gorget and reports that it measures 16.35 cm in length. The green discoloration on the lower right and upper left corner of the gorget is the traces of a copper stain. Phillips and Brown (1984: Plate 338A) and Brown (1996:594) assign this gorget to Craig C style. Described and published by Brown and Hamilton (1965: 55, Figure 4) as an oblong gorget with the "cross-in-circle" motif.
