Ogham Boulder?

High up on Ramshaw Rocks overlooking the A53 Leek to Buxton road in the Staffordshire Moorlands, close to where a Celtic face carved into one of the rocks can be found, close to this boulder can be found another which bears strange markings upon it. According to Frank Parker, local author and expert on the area having lived around here for most of his life, it is his opinion that these markings could be ancient Irish writing known as Ogham. This writing probably dates back to around the 5th century and is thought to consist of lines and dots etched into the edges of standing stones, the vertical line would have been drawn first, and all the side lines are drawn going vertically down a continuous mid-line. It usually consisted of up to five lines on any one side because it evolved from a finger language. Which side of the line depended on the right or left hand. It was adopted by the picts on the British Isles, but their language is totally unknown so the Ogham texts remain undeciphered to this day.
