2. How do we calculate a mountain's prominence?First find the mountain’s summit. Then find the lowest point on the ridge that leads to a higher peak, called the key col. The prominence is the height difference between the summit and that key col.
3. Why do some mountains have a high prominence?A high prominence means the mountain is far away from taller mountains and has deep valleys or saddles around it. It shows the mountain is very isolated and stands out in the landscape.

Topographic prominence: A quantitative measure of a mountain's isolation and dominance relative to its surrounding terrain.
Key col: The lowest elevation point on the ridge connecting a summit to its parent peak.
Parent peak: The nearest higher summit to which a given peak is connected via a col.
