Geocache Description:

Danger! Please Keep in the Path.

Yehliu GeoPark

Yehliu is a long cape on the north coast of Taiwan in the town of Wanli between Taipei and Keelung. The cape, known by geologists as the Yehliu Promontory, forms part of the Taliao Miocene Formation. It stretches approximately 1,700 meters into the ocean and was formed as geological forces pushed Datun Mountain out of the sea. Because the rock layer of nearby seashore contains limestone subject to sea erosion, weathering and earth movements, a distinctive feature of the cape is the hoodoo rocks that dot its surface in the shape of mushroom, candle, ginger, and the chessboard.

Landscape Distribution

Evolution process
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 stong northeastern monsoon.

Muchroom rocks Muchroom rocks
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. Among them, the famous Queen's Head demonstrates majestic elegance. It now becoms the landmark of Yehliu Geology Park.

Candle rocks Candle rocks
Candles shaped rocks here were carved by sea erosion. After the softer surfae 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.

Honeycombed rocks Honeycombed rocks
Honeycombed rocks refer to mushrrom shaped crags whose surface is filled with sea eroded holse of different sizes. The Weathering Window, the Marine Bird Rock, and the 24- Filial-Piety Hill are the best-known among them.

Ginger rocks 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 Shose is most famous among them. You would almost believe that it was left in a hurry by a fairy.

Pot holes 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.

Chessboard Chessboard rocks
In the coast area between Fairy's Shose and the ligthhouse 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.

Fossils 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 th ecrab's motion, like sand pipe fossil, it is belong to the trace fossil.

1. What kinds of minerals between rock layer of nearby seashore, subject to sea erosion, weathering and earth movements?
2. Estimate the height of Queen's Head muchroom rocks.
3. Estimate the diameter of most thinest part of Queen's Head. (Don't touch it. Use your eye.)
