At one time in the 1960s or so, someone made a small cross which was erected at the site. Several kinds of lichen found on the cross helped identify the time frame when it was made. The first excavation at the cross site revealed only small items. These included bones, wax pieces, broken wide-mouthed bottles, strange foil, and parchment fragments. Extensive research was conducted on these materials. Also on the water flow in the arroyo.
