A spokesman from the Snowdonia National Park Authority was pleased by the new height, and suggested that now the mountain exceeded 1,000 m, it was sure to attract more walkers to the area.

[3] The Glyderau range was formed about five hundred million years ago, when two land masses collided, causing the Snowdonia massif to rise up.

Since then, wind, water and frost, and the advance and retreat of glaciers during the ice ages have gradually worn down the mountains to their present proportions.

The ice scarred the surrounding cliffs, hollowed out the bed of Llyn Idwal and dumped rocks and other material that formed moraines at its foot.

There are eight tenanted farms on the estate, and the National Trust is responsible for the maintenance of footpaths and drystone walls, some of which date back many hundreds of years.
