The Gravel Pit

Some gravel they didn't find

The Gravel Pit was no doubt abandoned when they'd extracted all the gravel that was economical to extract. However, a natural fissure in the ground which has been enlarged by erosion has opened up a canyon to the northeastern end of the valley. Here in the canyon wall you can clearly see a seem of gravel that the miners missed. To the left you can see the red clay, but to the right, under a thin layer of red clay topsoil you can see gravel buried in gray clay.
