The sun lifts them off. They will fill with windblown seeds in the next few weeks, then close up again with summer thunderstorms.

And the elms (an invasive species filling some missing niches) sprouts like the dickens on the edges, where the damp remains..

In the end, there will be a grove of trees, and a band of herbaceous plants along their edge in the sun. Upslope, there will be escape terrain for deer, a good tumble of rock as shelter for herbs, snakes and small mammals and as rooting ground for shrubs.
