July 20, 1980 - One of My Very Favorites (almost 3-D)
Early evening, July 20 (or 21?), 1980, Southeastern Perkins County, South Dakota (about 20 miles north of Faith, SD, as the crow flies).
Thunder Butte is visible on the northeast horizon, about 18 miles distant. You need to study it at its largest size.
I truly love this picture.
