Brigham Young teaches the Flood was the baptism of the earth.
Brigham Young, "True and False Riches," Journal of Discourses, 26 vols. (Liverpool: F. D. and S. W. Richards, 1854), 1:274
Here are the earth and the inhabitants upon its face, organized for the express purpose of a glorious resurrection. The terra firma on which we walk, and from which we gain our bread, is looking forth for the morning of the resurrection, and will get a resurrection, and be cleansed from the filthiness that has gone forth out of her. This is Bible doctrine. What filthiness has gone forth out of her? You and I, and all the inhabitants of the earth; the human body, and all earthly bodies, both animal and vegetable; are composed of the native element that we breathe, that we drink, and that we walk upon; we till the earth for our bread, which is one of the materials of which your body is composed, it comes forth from the native elements into an organized state; what for? To be exalted, to get a glorious resurrection. We are of the earth, earthy, and not only will the portion of mother earth which composes these bodies get a resurrection, but the earth itself. It has already had a baptism. You who have read the Bible must know that that is Bible doctrine. What does it matter if it is not stated in the same words that I use, it is none the less true that it was baptized for the remission of sins. The Lord said, “I will deluge (or immerse) the earth in water for the remission of the sins of the people;” or if you will allow me to express myself in a familiar style, to kill all the vermin that were nitting, and breeding, and polluting its body; it was cleansed of its filthiness; and soaked in the water, as long as some of our people ought to soak. The Lord baptized the earth for the remission of sins, and it has been once cleansed from the filthiness that has gone out of it, which was in the inhabitants who dwelt upon its face.
