Slate tooth slabs form the almost gravestone-like pathway to congregation from Conglog quarry near Blaenau Ffestiniog in Wales to Capel y Gorlan, a place of worship for the collective quarries in the area, including the much bigger Rhosydd quarry a little further to the west. Built in the mid 1800s, prayer meetings were held every other Tuesday evening, alternating with the Fellowship meetings. Seen in the distant center of the above photo, it is believed that the chapel was closed sometime around 1929 when the quarrymen had slowly left the area, but is still just about standing today. Like much of the slate landscape, very little has changed in the years that followed. They are now officially classed as a unesco world heritage site, and for good reason. You'll struggle to find a more eternal partnership between man and nature anywhere in the world. The archive image is believed to be taken in 1929 around the time when the quarries closed.
