Joseph Smith, in a sermon from 1839, teaches that he had a vision of Adam in the valley of Adam-ondi-ahman.
Discourse, between circa 26 June and circa 4 August 1839–A, as Reported by William Clayton, 15, The Joseph Smith Papers website, accessed December 16, 2022
I saw Adam in the valley of Adam-ondi-ahman, he called together his children and blessed them with a Patriarchal blessing. The Lord appeared in their midst and he (Adam) blessed them all and foretold what should befall them to the latest generation See D. C. Sec. 3— 28, 29. This is why Abraham blessed his posterity.
