Flower Island Introduction
The volcanic rock geology of the Penghu Islands is primarily basalt, with the only exception being Huayu Island, which is composed of andesite. Andesite is formed from volcanic magma that cools quickly, resulting in a rock with high viscosity and slow flow. It typically accumulates around the volcano's crater in a conical shape, unlike the rectangular terrain formed by basalt. This island was formed approximately 65 million years ago, making it the oldest and westernmost island in Penghu. Huayu Island is located northwest of Wang'an Island and is home to nearly a hundred species of native plants, which is why it is named "Huayu," meaning "Flower Island." Currently, there are only a little over a hundred residents, as the area is abundant in fishery resources due to the convergence of the Kuroshio Current and the Taiwan Current, with the local population primarily engaged in fishing. The highest point on the island is Yandun Mountain, which rises 53 meters above sea level. On the western side of the mountain, the Huayu Lighthouse stands tall; it is built of reinforced concrete and is the westernmost lighthouse in Taiwan, serving as an important landmark of Huayu. On the southeastern rocky shore, there are also the legendary "footprints" of Lü Dongbin, with the left foot imprint located here matching the right foot imprint found on Tiantai Mountain of Wang'an Island, though they are only visible during low tide!
