Youthful drivers or streams are typically found in the highland or mountainous areas. They are characterized by steep slopes, a relatively small volume of water and rapid flow. Soil particles carried by youthful streams flow along the ground, wearing downhill slopes as the water flows down.

In this youthful stage of the river, such features as small lakes, waterfalls, rapids, V-shaped valleys, gorges and interlocking spurs are frequently found.

In geology, a nappe or thrust sheet is a large sheet-like body of rock that has been moved more than 2 km or 5 km from its original position by faulting or folding.

They form when a mass of rock is forced (or 'thrust') over another rock mass, typically on a low angle fault plane. The resulting structure may include large-scale recumbent folds, shearing along the fault plane.
