Well-known as Fengluling, it refers to a large crater in the south of the Volcanic Cluster owing to its resemblance to draft furnace. The crater never suffers from waterlog, as the walls are covered with natural wild vegetation at a height of 69m, falling into four categories, specifically trees, shrubs, ferns and mosses from top to bottom. The last eruption of Fengluling Volcano happened around 8000 years ago, with morphology of crater bottom, inner crater slope, crater wall, outer slope of crater cone, foot slope and scarp, etc. Steep crater wall mainly consists of vesicular olivine basalt and pyroclastic rock. Pumice, shell lava, ropy lava and other volcanic rocks are visible in the lava flow of volcano.
