Results provide a maximum possible age, a minimum age, and an exposure time window for the creation of the Great Gallery panel, respectively.
The only prior hypothesis not disproven is a late Archaic origin for BCS rock art, although our age result of A. ∼1–1100 coincides better with the transition to and rise of the subsequent Fremont culture.
Recent OSL dating of stone tools in Arabia pushed the "out-of-Africa" date hypothesis of human migration back 50,000 years and added a possible path of migration from the African continent to the Arabian peninsula instead of through Europe.
Key physical relations between the famous Great Gallery rock art panel in Utah, stream deposits, and a rockfall that removed some art, allow us to disprove all but a late Archaic hypothesis for the age of this type section of the Barrier Canyon style.

If the centre with the hole is a luminescence center (radiative recombination centre) emission of light will occur.
Use of a new luminescence profile technique on the same rockfall furthermore outlines a window of time A. ∼1 to 1100 when the figures could have been painted, generally more recent than expected.
Our study illustrates novel and widely applicable approaches for dating rock art that do not require destructive sampling, and results suggest that Barrier Canyon rock art persisted across the transition from the late Archaic into the agrarian Fremont culture in the American Southwest.
It is also used for dating the deposition of geological sediments after they have been transported by air (aeolian sediments) or rivers (fluvial sediments).
In archaeology, OSL dating is applied to ceramics: The dated event is the time of their last heating to a high temperature (in excess of 400 °C).
