Yakima Fold Belt

The Yakima Fold Belt is a series of large, gently folded rock formations located in south-central Washington. These folds formed over millions of years due to tectonic forces that caused the Earth's crust to buckle and bend. The resulting ridges and valleys create a distinctive landscape characterized by elongated ridges called ridges and intervening valleys. The folds are part of a broader geological process related to the ongoing collision of the Pacific and North American tectonic plates, which continues to shape the region's terrain and can influence seismic activity.
