The Roaring Fork Valley is part of the larger Roaring Fork Watershed, which includes the Fryingpan and Crystal River valleys. The valley extends for approximately 50 mi (80 km) southeast to northwest from Aspen northwest to Glenwood Springs at the mouth of the Roaring Fork on the Colorado River, ranging in width between 1 and 5 mi (1.6 and 8.0 km).
Basalt columns seen on Porto Santo Island, Portugal. Columnar jointing of volcanic rocks exists in many places on Earth. Perhaps the most famous basalt lava flow in the world is the Giant's Causeway in Northern Ireland, in which the vertical joints form polygonal columns and give the impression of having been artificially constructed.
The Colorado Province took shape as a mobile belt—an area of thinner, orogeny related continental crust lacking the deep "keel" of rock, which stabilized the neighboring Wyoming Craton and other cratons like it. Throughout Colorado's geologic history, rocks have often been deformed, metamorphosed and overprinted, obscuring the ancient record.
Tataga-Matau Fortified Quarry Complex (AS-34-10), near the village of Leone on Tutuila in American Samoa, NRHP-listed, "a complex consisting of a series of basalt quarries and structures that archaeologists have interpreted as having a military defensive purpose. The site has been known since at least 1927, and was first formally surveyed in ...
Columnar jointing is a geological structure where sets of intersecting closely spaced fractures, referred to as joints, result in the formation of a regular array of polygonal prisms (basalt prisms), or columns. Columnar jointing occurs in many types of igneous rocks and forms as the rock cools and contracts.
Basalt (UK: / ˈ b æ s ɒ l t,-ɔː l t,-əl t /; [1] [2] US: / b ə ˈ s ɔː l t, ˈ b eɪ s ɔː l t /) [3] is an aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the surface of a rocky planet or moon.
