Arthur's Seat is the main peak of the group of hills which form most of Holyrood Park, a remarkably wild piece of highland landscape in the centre of the city of Edinburgh, about a mile to the east of Edinburgh Castle. The hill rises above the city to a height of 251 m (823 feet), provides excellent panoramic views of the city, is quite easy to climb, and is a popular walk. Though it can be climbed from almost any direction, the easiest and simplest ascent is from the East, where a grassy slope rises above Dunsapie Loch.
Like the castle rock on which Edinburgh Castle is built, it was formed by an extinct volcano system of Carboniferous age (approximately 350 million years old), which was eroded by a glacier moving from west to east during the Quaternary, exposing rocky crags to the west and leaving a tail of material swept to the east. This is how the Salisbury Crags formed and became basalt cliffs between Arthur's Seat and the city centre. From some angles, Arthur's Seat resembles a sleeping lion.
Arthur's Seat and the Salisbury Crags adjoining it helped form the ideas of modern geology as it is currently understood. It was in these areas that James Hutton observed that the deposition of the sedimentary and formation of the igneous rocks must have occurred at different ages and in different ways than the thinking of that time said they did. It is possible to see particular area known as Hutton's Section in the Salisbury Crags where the magma forced its way through the sedimentary rocks above it to form the dolerite sills that can be seen in the section.This article is licensed under the GNU Free Documentation License.
