Cromarty Firth firth. Cromarty Firth The Cromarty Firth (; ; literally "kyles <nowiki>[</nowiki>straits] of Cromarty") is an arm of the Moray Firth in Scotland. The entrance to the Cromarty Firth is guarded by two precipitous headlands; the one on the north 151 metres high and the one on the south 141 metres high — called "The Sutors" from a fancied resemblance to a couple of shoemakers (in Scots, "souters") bent over their lasts. From the Sutors the Firth extends inland in a westerly and then south-westerly direction for a distance of 19 miles (30.6 kilometres). Excepting between Nigg Bay and Cromarty Bay
Pentland Firth Pentland Firth The Pentland Firth (, meaning the Orcadian Strait) is a strait which separates the Orkney Islands from Caithness in the north of Scotland. Despite the name, it is not a firth. The name is presumed to be a corruption of the Old Norse "Petlandsfjörð", meaning "the fjord of Pictland", and is completely unrelated to the Pentland Hills near Edinburgh. Prior to the Norse occupation of Orkney the strait was known as the "Sea of Orcs" – a reference to the Pictish tribe who inhabited Orkney. Such was their marine prowess that there are also instances of this name
