At the turn of spring and summer in 1921, ancient glacier relics in Shayuanling area of Shahe city in Hebei Province was first discovered by Mr. Li Siguang. The study of glaciology in China has been initiated. Since then, the debate on the existence of Quaternary glaciers in eastern China has continued for a century. In order to further study glacial relics of Shayuanling, field investigations, sample collection and dating work have been carried out. It is showrf that accumulated bodies in Shayuanling area have the characteristics of mixed size and non layered accumulation. Gravel composition is complex, with angular and sub angular shapes. The polished surface and various types of scratches on the surface of glacial moraine are developed, and there are typical wedge-shaped scratches, which are typical characteristics of glacial deposits. They are remnants of glacial processes. It is indicated that genesis judgment 100 years ago presented by Mr. Li Siguang's was accurate and reliable, without any misjudgment. According to geomorphological survey of the upper reaches of Shayuanling area, it was found that there is a small ice sheet centered around Liushigang, and a large number of "Icelandic style" U valleys remain on it. At the intersection of Shahe River and Mahui River, there is a typical "Arctic shaped zigzag ridge" in Xinghuazhuang. They indicate the existence of ancient ice caps in the upper reaches of Shayuanling. Based on the research results of glacial landforms and mountain uplift, combining with comparative study of multiple stratigraphic divisions in Hebei province, it is judged that glacial moraine accumulation time of Shayuanling is in early Oligocene. It belongs to residual glacial moraine accumulation of Laofu Ice Age.
