What mountains are associated with the key transportation route of the Elbe River?

The Krkonoš Mountains, also known as the Giant Mountains, are indeed associated with the Elbe River, which originates in this mountain range. Located on the border between the Czech Republic and Poland, the Krkonoš Mountains play a crucial role in the hydrology of the region. The Elbe River flows from these mountains through various landscapes, including valleys and plains, as it travels northwest toward the North Sea. The mountainous terrain influences the river's flow and serves as an important geographic feature that impacts transportation and movement in the area.

In contrast, Mount Kilimanjaro is located in Tanzania, the Rocky Mountains are found primarily in North America, and the Andes Mountains stretch along the western edge of South America. These mountain ranges do not have a direct relationship with the Elbe River or serve as a transportation route associated with it.
