Qomolongma (Mt. Everest) and the Big Island of Hawai'i both get hype as Earth's greatest mountain, but there's a mountain in the Caribbean Sea that beats them both in terms of sustained steepness. Its long-distance slope steepness from the base of the Cayman Trench to its summit is exceeded nowhere else on the planet over. This mountain probably pushes the limits of what Earth's rocks can support under the force of Earth's gravity. It's on the south coast of Cuba, and most people haven't even heard of it.
