Marker?

I needed some air today, though it was one of those walks where you walk with a thick frown on your face, wondering when you'll learn that drinking too much on an empty stomach is a mistake, and trying walk off the horrible way you now feel. Immersing myself in the forest I hoped to take my mind of my woes. I've mentioned before that when you immerse yourself in your walk, immerse yourself in the landscape you're walking through you start to see more. And when you walk a landscape long enough you'll notice anything out of place. Walking through the tall majestic beech of Church Moor this afternoon my eye was caught by a pile of stones amongst the leaf litter at the base of one of the beech. You get plenty of piles of stones in the forest, after all, the forest overlays gravels, sands and clays. But, this pile looked out of place.  As I walked over I saw stones of colours and types which were alien to those found locally. There were quartz, and lots of rounded pebbles amongst others. I can only assume that they had been placed here on purpose; a marker or memorial most likely.  A special spot to someone, imbued with meaning.
