HuMPs

Download More Relative Hills of Britain

A hill is classified as a HuMP if it is a hill of any height with a drop of at least 100 metres or more on all sides. The name HuMP stands for Hundred Metre Prominence.

A Twin HuMP is defined as a summit of equal height to another HuMP where the drop between the two summits is at least 30m but less than 100m.

A free e-book More Relative Hills of Britain (Adobe/PDF, 13.4MB) was originally announced by Mark Jackson on the Relative Hills of Britain Yahoo Group and is still available to download.

There are currently 1426 HuMPs and 4 Twin HuMPs in our database.
