Da Feng Volcano Neck Introduction
The volcanic region of eastern Taiwan and the offshore islands is the northern extension of the Luzon volcanic arc. The landscape resulting from volcanic activity along the eastern coast is diverse and commonly encountered, including various igneous rock formations in Green Island and Orchid Island, as well as the andesite columnar jointing at Wushi Harbor, all of which serve as invaluable geological educational resources. The Dapengfeng volcanic neck is a significant geological formation for research, located on the eastern coast near Zhangyuan Village, between Hualien County and Taitung County, and is currently managed by Taitung County. The landward area features two prominent rock formations, one being a consolidated mass of rock, while the other is a basalt with fan-shaped columnar joints, locally known as "Dajian Stone," representing a typical volcanic neck with columnar jointing. Near the coastline, a smaller sea-eroded platform formed by long-term wave action on the igneous rocks can be found. The Dapengfeng volcanic neck is remarkably complete, with unique frilled skirt-like tower columnar jointing similar to that found on Yuanbeidao in Penghu, presenting a unique landscape shaped by volcanic activity.
