The Hewitts

A Hewitt is "a Hill in England, Wales or Ireland over Two Thousand feet high (610m) with a drop of at least 30 metres (98 feet) all round".

The Hewitts of England and Wales are therefore a subset of the Nuttalls.

A sub-Hewitt is a hill which just fails (by up to 10m) to qualify on either the height or difference rule.

(Hewitts appear as Class=Hew on this website, and sub-Hewitts as Class=sHew).

The list was compiled and is maintained by TACit Press, who also publish a hillwalking fanzine, and other interesting stuff about mountains.
