- Relative Height
- Relative height, drop, or prominence is the height difference between a hill's summit and the col (lowest point) connecting it to the next higher summit. "Marilyns" are hills with a prominence of 150 metres, and "Humps" have 100 metres. There are some even in the south east of England. Hills which are not Marilyns are often subsidiary peaks of a higher hill.
