Baula

The peculiar looking mountain Baula, with its reddish or orange colour caused by its rhyolite rock composition, is situated in the west of Iceland next to Route 1 (the Ring Road). TheBifröst School of Business and the picturesque craters of Grábrók are located nearby.

Geologically, the mountain is classified as an "intrusion" (or, in geologist's terms, a "batholit," which is a mass of rock that has been thrust upwards from deep within the earth, to the surface). This thrust to the surface has been estimated to have taken place about 3.5 million years ago.
Baula is characterized by its almost perfect cone and by its little sister nearby, the Litla-Baula, where rare columnar strands of rhyolite are found. Together, Baula and Litla-Baula have often been described as Iceland's most beautiful pair of mountains.
Some other good examples of similar "intrusions" in Iceland include the mountains Mćlifell in the Snćfellsnes Peninsula and the Hlíđarfjall, near lake Mývatn in the north of the country.
