The best viewing time of trough

The best viewing time of the trough is April and May every year.

Wave Valley, also known as Jingbian Red Sandstone Canyon and Jingbian Longzhou Danxia landform, is located in Jingbian County, Yulin City, Shaanxi Province. On February 30, 2020, 65438+ was officially opened to the public, with a total area of 44 square kilometers as of 20265438+ 10/. It was formed in the Cretaceous period 96 million years ago and enjoys a worldwide reputation. Wave trough is a kind of red sandstone landform, so it is called wave trough because the lines on the rock sand are like waves.

About the formation of this strange stone, the relevant records say: The trough shows a wonderful world carved by millions of years of wind, water and time. The complex rock layers in Wave Valley consist of huge sand dunes that began to deposit in Jurassic one hundred and fifty millions of years ago. Dunes are often covered with red sand layers soaked in underground water. As time goes on, minerals in the water condense sand into sandstone, forming a layered structure.

The unique scenery of the trough

The so-called Langgu is located in Yanjiazhai Village, Longzhou Township, 22 kilometers southeast of Jingbian County, commonly known as Yanjiazhai Village. It takes half an hour to get to Daryun from Jingbian County. When I came to Langgu, I saw the red stone flowing like a mudslide, rushing into the ravine in circles, bumps and bends. This kind of stone is similar to a kind of sandstone, with severe weathering and falling off. Walking on it, if you are not careful, you will be slipped by the fine red sand attached to the epidermis.

Walking along the red stone beside the ditch, you can see a large and flat stone wall in a wide place, which is red from top to bottom and basically the same color. In a narrow place, the red stone appears as flowing water, like red mud, flowing to the bottom of the ditch. On the Longkou opposite Yanzhaizigou, the terrain here is relatively flat.
