Boring Lava Field subsurface regions near Aurora and Curtis, and these intrusions have been associated with normal faulting at Parrett and Petes Mountain, Aurora, Curtis, and Swan Island (along the Molalla River). Faults together with igneous intrusions are usually accompanied by stretching and doming as a result of magma influxes or collapses from the evacuation of the magma flows. Similarly, faults north of Oregon City might have resulted from subsidence after magma chambers emptied or lava was extruded as a result of Boring Lava eruptions. Some of the Boring lava vents are known to truncate hydrogeologic units in the surrounding area. Eruptive vents
Magma Geopark magma and high mountains. Through millions of years, glaciers helped to form the landscape we see in the area today. The main rock type is anorthosite, which is more common on the Moon than on the surface of Earth. Magma Geopark has several nature, culture, history and industrial attractions for both local visitors or tourists. The area has wide network routes and locations for outdoor activities, such as hiking, biking, climbing, kayaking. The geoVR virtual exhibition is now ready for the public in the centre of Egersund.
