One of the geographical information that we often see or hear about of towns is their elevation. Elevation is one of the factors that determines the climate of an area. Some cities are actually known by their elevation. For example, Denver, Colorado is known as the Mile-High City because it is a mile above sea level. For cities and mountains that are close to the ocean, elevation can be measured using general measurement tools and some calculations, but what if the location is many miles away from any ocean?

 How do you measure elevation when the town is in the mountains and very far from the nearest ocean?
