Flower Isle Introduction
The volcanic rock geology of the Penghu Archipelago is predominantly basalt, with the only exception being Huayu Islet, which is made up of andesite. Andesite is a type of volcanic rock formed by the rapid cooling of lava, characterized by high viscosity and slow flow, typically accumulating in a conical shape near volcanic craters, contrasting with the cubic mountain formations created by basalt. It was formed approximately 65 million years ago, making it the oldest and westernmost island in Penghu. Huayu Islet is located northwest of Wang-an, and the island is home to nearly a hundred species of native plants, which is why it is named Huayu (Flower Islet). Currently, there are only about a hundred residents, as the confluence of the Kuroshio Current and the Tsushima Current provides abundant fishery resources, with most residents engaging in fishing. The highest point on the island, Yandun Mountain, reaches an elevation of 53 meters, while a lighthouse is built on the western summit of the mountain. The Huayu Lighthouse, with its pure white tower constructed of reinforced concrete, is the westernmost lighthouse in Taiwan and an important landmark of Huayu. On the southeastern rocky area, there is also a legendary "footprint of the immortal" left by Lü Dongbin, where the left footprint aligns with the right footprint on Tiantai Mountain in Wang-an, but these can only be seen during low tide!
