Exploring the Mysteries of Death Valley

A close-up of an old, sepia-toned topographic map showing a grid of numbered squares and labeled geographical features like 'Megguire Valley' and 'Carnac's Sun.' A large, dark, irregularly shaped landform is centered in square 28, and the letter 'O' is superimposed over it in large, bold font. The map has a vintage, slightly worn appearance with fine lines and dot patterns indicating terrain.
