Moorfoot Hills

A disused quarry which formerly exploited an isolated granite intrusion sits to the west of the B7007 road at Broad Law.

To its southeast and parallel with it are three further NE-SW aligned reverse faults which are associated with the final stages of the closure of the Iapetus Ocean during the Caledonian orogeny, as are the sedimentary rocks which they affect.

Further east, a similar fault defines the course of the Dewar Burn and continues north through Peat Hill to Whitelaw Cleugh near the northeastern end of the main scarp.

[2][3] Since the last ice age, peat deposits have accumulated particularly around the plateau surfaces surrounding Blackhope Scar and Jeffries Corse.

The range runs from Peebles in the Scottish Borders, in a north easterly direction to Tynehead near the A7 road in Midlothian.
