Geology of Yehliu Geopark
Yehliu is located at Wanli of Taipei County with a long cape. Because the rock layer of nearby seashore contains limestone subject to sea erosion, weathering and earth movements, Yehliu is full of seawater-eroded holes as well as numerous rocks in the shape of mushroom, candle, ginger, and chessboard. All these make this 1,700-meter-long cape a geology park with rich ecological resources and a prosperous fishing village.

Cuesta (Monocline Structure)
Cuesta refers to a kind of ridge featuring a stiff slope on one side and a gentle slope on the other side. It is formed by gently tilted sedimentary rock strata as a result of orogeny.

Marine Process
Yehliu is located in the subtropics zone with a temperate and humid climate. Each year, the place is under the influences of Northeast monsoon and wave erosion for over a six-month period. The impact caused by weathering can be detected apparently on rocks, whereas the formation of strange rock landscapes is also due to the decomposition of the special rock layer as existed underground.

Weathering Process
Weathering is the decomposition of earth rocks through direct contact with the planet’s atmosphere, while the rocks may turn into sands, mud and soils due to the chemical changes of inner substances or physical function—heat expands; cold contracts.

Joints
During the formation process of sea cape, the rock layer is extruded by external force that causes the development of crevices. These crevices are called joints. Joints look very much like faults in appearance, yet the rock layers on both sides of the rupture surface do not generate relative movement along the said surface. Joints can be developed in various sizes; take those as found in Yehliu for example, they can be as small as the bean curd rocks or as large as the sea grooves. Some of them even can be served as brides that connect both sides of the land.

Mushroom rocks
Here you can see about 180 rocks in the shape of mushroom, as a show window of their eroding process- from no-neck, broad-neck, to narrow-neck ones. Touring this area makes you feel like walking in a wonderland. Among them, the famous Queen’s Head demonstrates majestic elegance. It now becomes the landmark of Yehliu Geology Park.

Evolution Process
Mushroom rocks have attracted the attention of most tourists visiting Yehliu. Originally these rocks had gone through sea erosion and, as time went by, the hard concretion came out to have experience the impact of wind, sun, rain, sea-water and strong northeastern monsoon. Today, mushroom rocks here demonstrate an eroding process- from no-neck, broad-neck, to narrow-neck ones.

Candle rocks
Candles-shaped rocks here were carved by sea erosion. After the softer surface had been scoured off, the ball-like concretion stood out in candlewick shape. Meanwhile, sea erosion had not only created a circular trench on the top but also encroached downward to shape a cone candlestick.

Ginger rocks
After the softer surface had been washed away as a result of long period sea erosion, the hard calcium concretion of rock were further squeezed by earth movement to take the shape of gingers. The Fairy's Shoe is most famous among them. You would almost believe that it was left in a hurry by a fairy.

Chessboard rocks
In the coast area between Fairy’s Shoe and the lighthouse lies a complete bean curd rock. Such square crags were pressed and squeezed as a result of weathering to show latticed joints. After long period sea erosion, these fissures form small lines of gutter, just like pieces of delicious bean curd.

Pot holes
Pebbles were brought by wave to wave-cut platform and then bumped deeper and deeper to form many pot-shaped holes. Inside these holes grow many seaweeds, small fishes and small crabs.

Sea erosion caves
During the process of ascending from under the sea, fragile layers of rocks or natural breaches on the cape had formed trenches due to sea erosion and gradually become a cave. Then the cave rose above sea level.

Weathering Ring
Weathering ring often appears as brown-color pattern on the surface of rocks, especially on the parts with cracks. The weathering ring shown on rocks can be regarded as pieces of extremely fine craftsmanship rendering flawless beauty with high ornamental value.

Fossils
There are plenty of fossils in the rock bedding, including the sea urchin fossil, which is in the petal shape and is belong to the body fossil; as well as to show the trace of the crabs' motion, like sand pipe fossil, it is belong to the trace fossil.

Geological protection
Tourists can clearly to see that rocks in the whole Yehliu area are still in lively and dynamic evolution. When you come here, be sure not to touch or even damage any of these creations of nature, so that our future generations can also enjoy them.
