Natural History
The national park's distinctive hard granite boulders and range originally formed out of magma that first slowly solidified under the Earth's crust about 250 million years ago.
The softer land surfaces above the solidified magma eroded away over time, leaving the magma's fractured top to be exposed as a mountain of grey granite boulders blackened by a film of microscopic blue-green algae growing on the exposed surfaces. Colder rains falling on the dark, heated granite boulders causes the boulders to progressively fracture, break, and slowly disintegrate, sometimes explosively.

Famous quotes containing the words natural and/or history:
“Our art is the finest, the noblest, the most suggestive, for it is the synthesis of all the arts. Sculpture, painting, literature, elocution, architecture, and music are its natural tools. But while it needs all of those artistic manifestations in order to be its whole self, it asks of its priest or priestess one indispensable virtue: “faith.””
—Sarah Bernhardt (1845–1923)
“History ... is, indeed, little more than the register of the crimes, follies, and misfortunes of mankind.
But what experience and history teach is this—that peoples and governments have never learned anything from history, or acted on principles deduced from it.”
—Georg Wilhelm Friedrich Hegel (1770–1831)
