天宝山穿洞位于东平河西岸，天宝山景点入口左侧山上。穿洞洞体宏大，呈近正方形，边长约20米，是东兰国家地质公园范围内最大、保存最好的天然穿洞。穿洞顶部有停止发育的钟乳石景观，底部有崩塌堆积物及多种珍稀植物，不仅展示了大自然的奥妙，也在向人们传递着地质演化的重要信息。
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.
伏流也叫暗河，因岩溶作用在大面积石灰岩地区所形成的溶洞和地下通道中，是具有河流主要特征的水流。主要在喀斯特发育中期形成，发育及其形态常受地质构造及裂隙的控制。东兰国家地质公园东平河在约拉区域形成了地下河与地表河交替出现的“四暗五明”伏流景观。
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.
东平河源自韦拔群故里东里三潭，由北向南流经那烈、巴学、江平至坤王穿入地下溶洞注入巴马盘阳河。全长29.5km，流域面积212.5km2。东平河自北向南贯穿武篆镇的千山万壑之中，奇峰突兀，碧水悠悠，处处皆景。两岸峰丛汇集了各种极具观赏价值的自然造型岩石。江水如玉带绕山，造就了江平美丽的田园风光。
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.
波痕构造是由风、水流或波浪等介质的运动在沉积物表面所形成的一种波状起伏的层面构造。按成因可分为浪成、流水和风成波痕三种类型，不同形状波痕的推移则产生不同类型的层理。波痕是典型的沉积构造，可作为分析沉积环境的重要标志。
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.
岩溶峰丛地貌是由基座相连，顶部为圆锥状或尖锥状的石灰岩山峰构成的地貌景观，主要分布在桂西、桂西北与云贵高原的边缘部分。峰丛之间，岩溶洼地、漏斗、落水洞发育，常形成峰丛洼地或峰丛漏斗的组合形态，以红水河上游最为典型。东兰境内有著名的兰木峰丛及弄英村峰丛，气势磅礴，宏伟壮观。
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.
峰丛洼地是有连座的正向石峰和其间的封闭洼地所组成的地貌景观。东兰地区的峰丛洼地景观广泛分布于武篆、兰木和泗孟，以泗孟田园峰丛洼地最为典型。洼地近圆形，底部平坦，并覆盖有溶蚀残余物，沿着溶蚀残余物形成数级梯田。落日下，峰丛与梯田交相辉映，宛若一幅精致的画卷，让人流连忘返。
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.
位于东平河西岸，穿洞近似圆形，高约15m，宽约10m，绝对海拔约390m。由于周围山体的遮挡，随着远观角度的不同，穿洞则呈现如同月亮阴晴圆缺的形状，因而得名“月亮山穿洞”。
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.
早期，地壳抬升，裂隙发育，地下河水溶蚀山体，将山体内部掏空，形成地下溶洞。在流水长时间冲刷作用下，溶洞所在山体发生坍塌，最终前后相通。后因地壳继续抬升、地下水位不断下降而逐渐显露于地表，形成似月亮形状的月亮山穿洞。
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.
位于东平河东岸、公路边山上，上部呈正三角形，整体高约10米，宽约3米，绝对海拔约360米。远远望去，穿洞所处山体像一头昂首挺立、温和憨厚的大象，漫步峰丛，悠然自得，故而得名“小象山”穿洞。
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.
东兰国家地质公园岩溶地貌发育，形成了大大小小的穿洞。穿洞分布密集，延展方向有序，蔚为壮观。高低错落的溶洞，在流水长时间的侵蚀作用后，形成千姿万态、美轮美奂的穿洞，让人无不惊叹大自然的鬼斧神工。
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.
东兰国家地质公园穿洞发育，形成的穿洞群有着重要的地学意义。穿洞群对研究东平河早期河流的演化具有关键作用，对探讨桂西北岩溶山区和红水河流域协同演化的历史和生态环境也具有不可估量的科研价值。
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.
驼吻峰穿洞位于东平河西岸，早期为地下溶洞，经水流长期冲刷，溶洞逐渐溶蚀、坍塌，前后相通，后因地壳抬升、地下水位下降出露于地表。穿洞所处山体外观像温文尔雅的骆驼俯身亲吻眼前的山峰故而得名“驼吻峰”穿洞。
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.
