Basalt is a medium to dark gray, fine grained igneous rock – similar to granite in durability. As a fine-grained extrusive equivalent of gabbro, igneous stones (granite, syenite, diorite, gabbro, andesite and basalt) are formed when magma, or molten rock / lava, within the earth cools.  The earth’s largest supply of Basalt stretches through the Columbia River area in the states of Washington, Oregon, and Idaho to distant areas of China, India, Namibia, South Africa, and the Siberian area of Russia.

Basalt is freeze resistant and used for a wide variety of purposes including crushed aggregate road base, concrete aggregate, asphalt pavement aggregate, railroad ballast, filter stone in drain fields, and may other purposes.
