The Underwater Forest (2017)

The forest appears to be a wholly unique relic of our planet's past, the only known site where a coastal ice age forest this old has been preserved in place, with thousands of trees still rooted in the dirt they were growing millennia ago. It is considered a treasure trove of information, providing new insights into everything from climate in the region to annual rainfall, insect populations, and the types of plants that inhabited the Gulf Coast before humans arrived in the new world. Scientific analysis of the site is ongoing. One of the key things the forest might hint at is a world where the seas rose even more quickly than the worst-case predictions for the near future. The film was written and directed by Ben Raines and narrated by Ian Thompson-Yates.
