Chapter artwork from The Lord of the Rings, book 6 chapter 3, Mount Doom.

This design focuses on the visual description of Mount Doom, also known as Orodruin, and pulls heavily from Tolkien's own illustration of the volcano, as you can see below.

“Smokes were pouring from it, and while those that rose into the upper air trailed away eastward, great rolling clouds floated down its sides and spread over the land.”

“The confused and tumbled shoulders of its great base rose for maybe three thousand feet above the plain, and above them was reared half as high again its tall central cone, like a vast oast or chimney capped with a jagged crater.”
