航点01的信息板教给你一些有趣的事实：
The information board at waypoint 01 teaches you some interesting facts:
大约4亿年前，这里形成了砂岩地层。大约2.5亿年前，碳酸盐岩形成如石灰岩和白云石。地壳大约在2.1亿年前升起为土地。
About 400 million years ago, quartz sandstone strata were formed here. Some 250 million years ago carbonate formation like limestone and dolomite developed. The crust uplifted to become land about 210 million years ago.
大约6500万年前的喜马拉雅运动在这里形成了一个三级平面。它们分别为1200米，1000米和800米ASL。
The Himalayan movement dated from about 65 million years ago has formed a three-level planation surface here. They are at 1200m, 1000m and 800m ASL.
间歇地，地壳抬升，石英砂岩上方的盖层被侵蚀掉了。沿着一些交错的关节，流动的水在地层中被切割，并将古老的平面表面分成主要的台地和不同大小的峰形脊。沿着关节，边缘部分被分成岩石堤坝和石柱的基础。这个阶段的代表性地形是台地平原。
Intermittently, the earth's crust uplifted and the cap strata above the quartz sandstone were eroded off. Along some interlaced joints flowing water cut down in the strata and split the ancient planation surface into primary mesas and peak shaped ridges of different sizes. Along joints the marginal parts were split into the rudiments of the rock dykes and the stone pillars. The representative landform of this stage is the mesa plain.
区域倾斜和隆起导致溪流进一步削弱。这与向前侵蚀交替起作用，这增加了流网络的密度。台地平原进一步发展，沿垂直关节岩体坍塌。形成了山谷，石柱，高峰森林，堤坝，天然桥梁和拱门。
Regional tilting and uplift resulted in further undercutting by the streams. That worked alternately with headward erosion which increased the density of the stream network. The mesa plain further developed and along vertical joints rock masses collapsed. Valleys, stone pillars, peak forests, dykes, natural bridges and arches were formed.
当地壳处于相对稳定的状态时，砂岩峰林区的岩体由于风化和重力而坍塌。溪流横向侵蚀了河岸。由此，岩石碎片被冲走并积累。峰和柱逐渐变得越来越小。
When the earth's crust is in a relatively stable state the rock masses in the sandstone peak forest area collapse due to weathering and gravity. The streams erode the banks laterally. By that rock pieces are washed away and accumulated. The peaks and pillars gradually become shorter and smaller.
请至少回答以下三个问题并在登录前将其邮寄给我（您将在航点上获得董事会的帮助）：
a）描述植物生长如何影响表面外观的变化！根据您自己的观察解释你的答案！你可以证实你的发现在照片
b）横向或向下发生河流侵蚀。哪一个在金鞭谷的建设中占主导地位？哪些观察导致你的答案？
c）根据给出的解释，悬崖是如何形成的？提到至少两个方面！你可以在金色的谷谷看到这一点？
d）解释崩塌岩石发生的原因！为什么他们可以在这里轻松形成 ?
e）沟壑是如何形成的？为什么你认为开发沟壑的条件在这里是理想的？
Please, answer at least three of the following questions and mail them to me before logging (You will get help from the boards at the waypoints):
a) Describe how plant growth impacts the changes in the appearance of the surface! Explain your answer according to your own observation! You can substantiate your findings in a photo.
b) Fluvial erosion happens laterally or down-cutting. Which one is predominant in the building of the Golden Whip Valley? Which observations lead on to your answer?
c) How is a cliff formed according to the explanation given? Mention at least two aspects! How can you see this in the Golden Whip Valley?
d) Explain the reasons for the occurrence of colluvial rocks! Why can they easily form here?
e) How is a gully formed? Why do you think conditions for developing a gully are ideal here?
为了证明您确实在这里，请在信息板中说出英文文本的最后一个字 "Colluvial Rock" (waypoint 05)!
To prove that you were actually here, please tell the last word of the English text in the information board "Colluvial Rock" (waypoint 05)!
享受你的散步和“快乐狩猎”!
Enjoy your walk and "Happy hunting"!
