Definition
A firth is a long, narrow indentation of the sea coast, often formed by a river valley that has been submerged. It's similar to a fjord, but typically wider and shallower. Think of it as a watery embrace of the land, where the sea gently fingers its way inland. Unlike a dramatic cliff-lined coast, a firth offers a more gradual transition between land and water. It's a place of calm waters and scenic views. π
