Got most of this third hand-It is unconfirmed. The aztec's were probably carrying one of the idols with the Spanish in pursuit. There was a battle in S.W. Colorado in Paradox canyon on the San Miguel River.During the battle, the idol was transported down river. Confirmed portion-Pictographs recorded an idol being transported and an aztec warrior holding up a spanish shield. The rancher on who's property the pictographs were located has long since passed away and his son sold the rock with pictographs prior to selling the ranch. As best as I can remember,The rock was at least four feet square and about ten feet tall. The old rancher LOVED the land and was a conservator of it and the indian artifacts but his son was only interested in the money. I understand that there were at least three of the smaller idols, 250 pounds and one large idol. Hope this helps. Have fun! Jim
