Today you will learn about the South Ural Reserve, which is composed of multiple ridges, arranged parallelly from southwest to northeast, and the vast valley and cross-river divide it into the "field" structure. The area is not completely frozen into ice, but there are signs of freezing in the mountains and in parts of the plateau. All rivers here can be divided into small rivers or streams, the longest of which is the 93 km Little Inzer River, which runs through the entire protected area; The streams flow rapidly across the rocky riverbed. There are also several small marshes in the reserve. The South Ural Reserve is surrounded by woodland. This reserve has been affected by continuous economic activity. The area was home to iron foundries in the 18th and 19th centuries, where trees were cut down and rivers contaminated to supply carbon kilns. Commercial logging was further expanded in the early 20th century; during the war several detention camps were built and a narrow-track railway was built.
