With the help of the Smithsonian’s natural and American history museums, satellite images were prepared of the topography extending from the church toward the north, across the river, just as the Alpha Stone indicated. Incredibly, the squiggly lines depicted the right canyons, in the right places, the line with eighteen markers carving a path up into the Sangre de Cristo Mountains. Determining distance had been the tricky part, but the dots along the curvy line that ended at the center of the Heart Stone seemed evenly spaced apart, which they’d taken as a clue.
