Tianbaoshan karst cave, is located on the west coast of Donping river, lies on the left side of the mountain which situated the entrance to Tianbaoshan scenic spot. The karst cave body is huge, which is approximately in square, with a length of 20 meters.It is the largest and the most well preserved natural karst cave within Donglan National Geopark. There are stalactite landscape on the roof which has stopped development, and many collapse accumulation and a variety of rare plants in the bottom, which not only shows the wonders of nature, but also conveys important information about geological evolution.
Subterranean stream, also known as underground river, has the main features of rivers which formed in karst caves and underground channels due to karstification took place in a large scale of limestone area. The streams are formed in the middle stage of karst development, and its development and shape are usually controlled by geological structures and cracks. In the Yuela region of Dongping river in Donglan National Geopark, there is a subterranean stream landscape of underground river and surface river appearing alternately, which also called as four times dark and five times bright river landscape.
The Dongping river originates from Donglisantan, Wei Baqun’s hometown.It flows through Nalie, Baxue, Jiangping and Kunwang river and then goes into the underground karst caves to Bamapanyang river from north to south, with a total length of 29.5km, and the basin area of 212.5km2.It runs through thousands of mountains in Wuzhuan town from north to south where towering peaks and clear water developed. What a beautiful scenery!A variety of natural rocks of great ornamental value get together in the peak clusters on both sides of the river . The rivers runs around the mountains like a jade belt, forming a beautiful rural scenery of Jiangping.
Ripple mark structure is a kind of undulating bedding plane structure formed by the movement of wind, water, wave and other media on the surface of sediments. According to its cause of formation, it can be divided into three types: wave ripple mark, flow ripple mark and wind ripple mark. Different types of ripple marks can cuase different types of bedding. Ripple mark is a typical sedimentary structure which can be an important symbol to analyze sedimentary environment.
Karst peak cluster landform is a geomorphologic landscape composed of conical or tapered limestone peaks, of which the base are connected with each other. It is mainly distributed in the edge of west and northwest of Guangxi, and yunnan-guizhou plateau. There usually formed a combination landscape of peak cluster depression or peak cluster funnel between peak clusters where karst depression, funnels and dolines developed, of which the most typical landscape is located in the upper reaches of Hongshui river. There are also famous Lanmu peak cluster and Nongyingcun peak cluster in Donlan region, which looks majestic and precipitous.
Peak cluster depression is a geomorphologic landscape composed by connected stone peaks and the enclosed depression in between. Most peak cluster depression landscape of Donglan region widely distributed in Wuzhuan, Lanmu and Simeng, among which Simeng is most typical. The depression is nearly round, with flat bottom and covered with corrosion residues. There formed several levels of terraces along the corrosion residues. Under the sunset, the peak clusters and terraces alternates with each other, like a delicate painting, which is really fascinating.
Moon mountain karst cave is located in west coast of Dongping river. This cave is near round, the hole of which is 15 m high,10 m wide, with a sea level of 390m. Shaded from its surrounding mountains, the caves appears to be different shapes, with different view angles, the same as the changes of the moon as it waxes and wanes, so hence the name Moon mountain karst cave.
In early stage, with the rising of crust and the development of cracks, the underground water eroded the mountain and hollowed the mountain, forming the underground cave. Under a long time of water erosion, the mountain where the cave lies collapsed and eventually connected the anterior and posterior cave. Later, as the crust continues to lift and the groundwater level drops gradually, a karst cave shaped like the Moon, called Moon mountain karst cave was formed.
Small elephant karst cave is located in east coast of Dongping river and on a mountain along a highway, the upper of which is equilateral triangle. This cave is 10 m high and 3m wide, with a sea level of 360 m. Looking from a distance, the mountain where located this cave looks like a mild and honest elephant heading its head, wandering towards the peak cluster leisurely, hence the name Small elephant karst cave.
With the development of karst landform in Donglan National Geopark, many karst caves in all sizes were formed. The caves are densely distributed and extends in an orderly direction, which is really spectacular. After a long time of erosion, the caves in different heights forms various and beautiful karst caves, which makes people can't hold their wonder towards the magic of nature.
Karst cave group formed by the development of karst cave in Donglan Nationa Geopark has important geological significance. It plays a key role in studying the evolution of early rivers in Donping river, and also has immeasurable value to explore the history of co-evolution and ecological environment in karst mountainous area of northwestern Guangxi province and Hongshui river basin.
Camel kissing peak karst cave is located in the west coast of Dongping river. In the early stage, it is a underground karst cave. After long time of water erosion, the karst cave was eroded and collapsed, and eventually connected the anterior and posterior cave. Later, as the crust lifted and the groundwater level dropped, it gradually rised to the surface. The mountain where the cave lies shapes like a gentle camel kissing the peaks in front of him, then the cave was named as Camel kissing peak karst cave.
