What part of Chult does this image depict?
It is found in Tomb of Annihilation, on page 9. Is it Aldani Basin?
The Soshenstar and Tath rivers flow out of this marshy upland basin, which is a popular feeding ground for dinosaurs and swarms of biting insects. Tall plateaus and walls of dense foliage enclose the marsh.
The description matches, but the image is not labeled, and is on a different chapter of the book.
