List of Nuttall mountains

This is a list of Nuttall mountains by height. Nuttalls are defined as peaks in England and Wales above 2000 ft in height, the general requirement to be called a "mountain" in the British Isles, and with a prominence above 15 m; a mix of imperial and metric thresholds.

The Nuttall classification was suggested by Anne and John Nuttall in their 1990 two–volume book, "The Mountains of England and Wales". The list was updated with subsequent revised editions by the Nuttalls. Because of the prominence threshold of only 15 m, the list is subject to ongoing revisions. In response, Alan Dawson introduced the Hewitts, with a higher prominence threshold of 30 m. This was the prominence threshold that the UIAA set down in 1994 for an "independent" peak. In 2010, Dawson replaced his Hewitts with the fully "metric" Simms, consisting of a height threshold of 600 m, and a prominence threshold of 30 m. However, both the Nuttall and Hewitt classifications have become popular with peak baggers, and both remain in use, and their respective authors maintain up to date lists, as does the Database of British and Irish Hills.

446 Nuttalls, with 257 in England and 189 in Wales. The first people registered as climbing all of the Nuttalls were Anne and John Nuttall themselves, in March 1990. A register of people who declare they have climbed all of the Nuttalls is kept by the Long Distance Walkers Association ("LDWA");, it totalled 302 names. On 16 September 2017, James Forrest completed all 446 Nuttalls in six months.

Coverage of Nuttalls
The table below of 257 English Nuttalls at October 2018, include:

1. All 180 of the Hewitts in England (by definition, a Hewitt is a Nuttall);

2. 51 of the 175 Marilyn mountains and hills in England;

3. All 4 of the 120 P600 mountains in the British Isles that are English (by definition, a P600 is a Nuttall).

The table below of 189 Welsh Nuttalls at October 2018, include:

1. All 135 of the Hewitts in Wales (by definition, a Hewitt is a Nuttall);

2. 53 of the 158 Marilyn mountains and hills in Wales;

3. All 8 of the 120 P600 mountains in the British Isles that are Welsh (by definition, a P600 is a Nuttall).

Nuttall mountains in England by height
Data is from the Database of British and Irish Hills ("DoBIH") in October 2018, and are peaks DoBIH marks as English ("E" and "ES"), and Nuttalls ("N"). John and Anne Nuttall update the list of Nuttalls from time to time, and the DoBIH also updates their measurements as more surveys are recorded, so these tables should not be amended or updated unless the entire DoBIH data is re-downloaded again.

Nuttall mountains in Wales by height
This list is from the Database of British and Irish Hills ("DoBIH") in October 2018, and are peaks the DoBIH marks as being Welsh, and Nuttalls ("N"). John and Anne Nuttall update the list of Nuttalls from time to time, and the DoBIH also updates their measurements as more surveys are recorded, so these tables should not be amended or updated unless the entire DoBIH data is re-downloaded again.
