Gilgal

The Gilgal Gardens in Salt Lake City features a Sphynx of Joseph Smith and a statue of the Bible’s Daniel with a boulder for a head. Some of the rocks in the garden are engraved with a series of numbers which form no comprehensible pattern — strange artefacts calling out from the past with an inscrutable message, like in that one Star Trek where the alien probe converts the Enterprise into one of their ancient palaces.
