Valley of Diamonds

Located in Subterranea, the Valley of Diamonds shined so bright that its glare could blind anyone who looked upon it. Such was the case for the Mole Man, who developed a radar sense to make up for his loss of sight.

Mister Fantastic and the Human Torch of the Fantastic Four once wandered into the Valley of Diamonds and fell unconscious. The Mole Man placed them in protective suits.
