This gully was the drain field below the old septic tank system for the house. It drains directly into the neighbour's yard (the neighbour who lived in this house in the 70's) in the forested area and into a pond behind their house. Buried in the leaves and dirt all along this gully is a lot of household trash dating back to whenever the house was originally built -- their main trash dump. Aside from the trees, there is a lot of poison ivy, bush honeysuckle, multiflora rose, and a huge vine of winter creeper.
