Berwyn range

The area is wild and largely vegetated by heather about one metre thick, with some acidic grassland and bracken.

The Berwyn range is crossed to the southwest by the B4391 Milltir Cerrig mountain pass at an elevation of 486 metres (1,594 ft).

Several other summits in the area are listed as Hewitts or Nuttalls, including Foel Wen ([ˈvɔil ˈwɛn], Welsh for white hill) and Mynydd Tarw ([ˈmɐnɨð ˈtæɾu], bull mountain).

The Berwyn range also played its part in causing King Henry II of England to turn back during his invasion of Gwynedd in 1165.

Since earthquakes are uncommon in the UK,[dubious – discuss] it was not generally recognized for what it was, and since a number of unusual lights in the sky had been observed the same evening, it was considered possible that an aircraft had crashed, or a meteorite had impacted.

[1] The area supports substantial populations of upland birds including raptors, such as the hen harrier (Circus cyaneus), merlin (Falco columbarius), and peregrine (Falco peregrinus) (about 14–18 breeding pairs of each species, 1%–2% of the total British population),[2] and for this reason it is a Special Protection Area classified in accordance with the European Union's Birds Directive.
