The Wushih Pi headland is part of Taiwan's Central Mountain Range which extends from Su-ao in the northeast to Eluanbi at the southern tip of the island, forming a ridge of high mountains and serving as the island's major watershed for rivers and streams. The mountains are predominantly composed of hard rock formations resistant to weathering and erosion, although heavy rainfall has deeply scarred the sides with gorges and sharp valleys. Taroko National Park, located on the mountainous eastern side of the island, has good examples of mountainous terrain, gorges and erosion caused by a swiftly flowing river.
