Pentland Hills

The Pentland Hills are a beautiful range of hills located southwest of Edinburgh, Scotland. They stretch for about 20 miles (30 kilometres) and cover an area of 35 square miles (91 km²). The hills run from Edinburgh towards the town of Biggar and the upper part of Clydesdale.

These hills are very important and have been made a Scottish regional park. This helps keep the natural beauty of the area safe and gives people great places to enjoy outdoor activities like walking and exploring nature. The Pentland Hills are a favorite spot for both local people and visitors to relax and enjoy the landscape.

Toponymy

The Pentland Hills are named after a small village called Pentland. The village's name was first recorded in the 1100s. It likely means "head or top end of the church or enclosure" in an old language called Cumbric. People began using the name for the nearby hills from the 1500s. The name of the Pentland Firth, a narrow sea channel near Scotland, is not connected to the hills.

Geology

The Pentland Hills are made from different kinds of rocks. In the southern and western parts, you can find sandstones and conglomerates from the Devonian period. These rocks are part of the Old Red Sandstone.

There are also igneous rocks, like basalt and andesite, mixed in with the sedimentary rocks. These rocks came from ancient volcanic activity. The oldest rocks in the area are mudstones, siltstones, and sandstones from the Silurian period. These are covered by younger rocks from the late Silurian to early Devonian periods.

The southeastern edge of the hills has a fault called the Pentland Fault. Another fault, the Cairnmuir Fault, runs through the middle of the range. Some hills, like West Cairn Hill and East Cairn Hill, are made from sandstones called the Kinnesswood Formation.

Many lower areas are covered with glacial till from the last ice age. You can also find old meltwater channels in places like Deer Hope and Green Cleugh.

Use

The Pentland Hills cover an area of 35 square miles (91 km²) and became a regional park in 1986. People enjoy many activities there, such as hillwalking, mountain biking, horse riding, golf, and there is an artificial ski slope at the Midlothian Snowsports Centre.

Most of the land is open grassland, with some areas of trees. The Ministry of Defence has a rifle range at Castlelaw. Several rivers, like the Water of Leith and the North Esk, start in these hills. There are also many reservoirs, such as Threipmuir, Harlaw, Glencorse, and Loganlea.

In the southern part of the hills is Little Sparta, a special garden made by the artist and poet Ian Hamilton Finlay.

History

There is evidence of old settlements in the area, such as a hillfort and a hidden underground room at Castle Law and another at Caerketton. The hills were likely settled, farmed, and protected long ago by local Celtic people.

The hills were the site of an event in 1666 after the return of King Charles II to the throne. During this time, a group of people called Covenanters, who were unhappy with the king's rules, were defeated in a small battle. This event was later called the Pentland Rising. It is remembered today by a grave known as the "Covenanter's Grave."
