That spring, Joseph Smith visited the site. He proclaimed there were either two or three (depending on subsequent interpretations) altars built by Adam at the site. One altar Smith called the "altar of prayer"; it was located by Wight's house on Tower Hill. It was described as "sixteen feet long, by nine or ten feet wide, having its greatest extent north and south. The height of the altar at each end was some two and a half feet, gradually rising higher to the center, which was between four and five feet high—the whole surface being crowning." The other altar—called the "altar of sacrifice"—was said to be a mile to the north on top of Spring Hill.
