Flies floating in the well water cast a brackish appearance on the scene, but the water otherwise looks fairly clear. A few yellow jackets are buzzing around, catching the escaping vapour above.
This water would probably be fine to use if I really needed more, but the intake hose on my water filter isn't quite long enough to reach the water. I chicken out and leave the water for the flies.
The frame of the well appears to be built of old railroad ties.
