On the morning of 14th July, seven members of Biggar Ramblers set out on a 7 mile circular walk to the Covenanter's grave. Starting in the small village of Garvald, the walk headed west for about half a mile before turning north, through Easton Farm and up to the end of the track below Black Law, which involved crossing two deep and fast flowing fords, and keeping an eye out for passing horses taking part in a riding event. At this point the group heard some of the history of the covenanters, and how the national Covenant was drawn up in 1638 in order to resist Charles 1's attempts to enforce royal control over the church in Scotland which resulted in over 50 years of persecution and bloodshed. In 1666, 1800 men attempted to enter Edinburgh to present their grievances. However, they were refused entry and while retreating to the Pentland Hills, were attacked in what is now known as the Battle of Rullion Green. The Covenanters received savage treatment which included the removal of heads and arms which were then displayed in an attempt to dissuade further unrest from the covenanters.

The group now continued up the hill, through grass and heather, eventually reaching the stone marking the covenanter's grave. One of the Covenanters managed to escape from Rullion Green and was found badly wounded by a shepherd called Adam Sanderson. Knowing he was dying he asked the shepherd to bury him in sight of his beloved Ayrshire hills. Sanderson carried out the covenantor's wish and erected a stone which is now in Blackmount Church. The present stone was erected in 1841.

Despite hearing of all the bloodshed, the group found this spot peaceful and tranquil. Skylarks were singing, and there were wonderful views in all directions, including over to the distant Ayrshire Hills. It was tempting to linger, but it was now time to return back to Garvald via Medwynhead and Medwynbank. Despite an uncertain forecast the weather remained fine for the whole walk which was enjoyed by all.
