More distribution of hill names in Scotland, Ireland, and N. England: (I.e. the word for 'hill')
The interesting Gaelic divide in the Highlands is the Sgor/Carn divide, with Sgor (and Sgurr) prevalent on the West, and Carn being popular in the North and East (esp. in Cairgorms.)

Both 'Ben' (and Beinn/Bheinn) and 'Meall' are common throughout the Highlands, both North and South. There are virtually none south of the Highland Boundary Fault (roughly).
Scots/Norse-origin words like 'Fell' and 'Law' dominate in the Southern Uplands/N. England and Law particularly on the East Coast.
Sliabh (or Slieve, in Ireland) is predominantly Irish, but a few Sliabhs have made their way across the water to the fringes of the West Coast. (and some outliers in Speyside!)
(There are lots more hill names [including many just called '... Hill'], but these stood out as having interesting regional distributions.)

TIL: The Gaels didn't give a second-thought to those who might have to write regular expressions to match hill name spelling variants. (C.f. Carn/Càrn/Càirn/Chàrn/Chàirn/Chùirn)
