This increased the rate of erosion and cut nearly all of the Grand Canyon's current depth by 1.2 million years ago. The terraced walls of the canyon were created by differential erosion. [33] Between 100,000 and 3 million years ago, volcanic activity deposited ash and lava over the area, which at times completely obstructed the river. These ...
Created from what used to be the security buffer surrounding the Hanford Nuclear Reservation, this area has been untouched by development or agriculture since 1943. The area is part of the Columbia River Plateau, formed by basalt lava flows and water erosion, and is named after the Hanford Reach, the last free flowing section of the Columbia River.
Natural features (consisting of physical and biological formations), geological and physiographical formations (including habitats of threatened species of animals and plants), and natural sites which are important from the point of view of science, conservation, or natural beauty, are defined as natural heritage.

The mounded prairie region is located on top of the plateaus, characterized by many species grasses and wildflowers around the vernal pools, with mounds of soil created by erosion. The dwarf woolly meadowfoam, a plant endemic to the Table Rocks, grows near these pools. [9] [37] [53] They bloom for about ten days in April. [60]

The cliff-lined southeastern slope (escarpment slope) of Cumberland Mountain was created by erosion along the breached side of the Powell Valley ...
[46] [47] [48] An inselberg is a prominent isolated residual knob or hill that rises abruptly from and is surrounded by extensive and relatively flat erosion lowlands in a hot, dry region. [49] Uluru is also often referred to as a monolith, although this is an ambiguous term that is generally avoided by geologists. [50]
