Death Comes for the Archbishop by Willa Cather:
While they were ascending the rock, deafening thunder broke over their heads, and the rain began to fall as if it were spilled from a cloud-burst. Drawing into a deep twist of the stairway, under an overhanging ledge, they watched the water shaken in heavy curtains in the air before them. In a moment the seam in which they stood was like the channel of a brook. Looking out over the great plain spotted with mesas and glittering with rain sheets, the Bishop saw the distant mountains bright with sunlight. Again he thought that the first Creation morning might have looked like this, when the dry land was first drawn up out of the deep, and all was confusion.
The storm was over in half an hour. By the time the Bishop and his guide reached the last turn in the trail, and rose through the crack, stepping out on the flat top of the rock, the noontide sun was blazing down upon Ácoma with almost insupportable brightness. The bare stone floor of the town and its deep-worn paths were washed white and clean, and those depressions in the surface which the Ácomas call their cisterns, were full of fresh rainwater. Already the women were bringing out their clothes, to begin washing. The drinking water was carried up the stairway in earthen jars on the heads of the women, from a secret spring below; but for all other purposes the people depended on the rainfall held in these cisterns.
