How high must a mountain be to be a mountain?

There is no universally accepted height that defines a mountain, as the distinction between a hill and a mountain can vary by region and culture. Generally, a mountain is often considered to be at least 1,000 feet (about 300 meters) high, although some definitions start at 2,000 feet (approximately 610 meters). Ultimately, the classification can also depend on local geographical features and perceptions.
