Greenwood Furnace State Park is a beautiful park near where I live in central Pennsylvania. During the nineteenth century, this park was the site of an iron furnace. Much of the forest around the furnace was cut down to provide fuel for the furnace. During the twentieth century, the forest grew again, and the Commonwealth of Pennsylvania acquired the land immediately around the furnace to establish a state park.

In the 1930s, the state built a dam in the park, creating a small lake for recreation. I have repeatedly gone to the park to photograph the lake and the Milky Way reflected in the water. My favorite time of year is autumn, when colorful leaves are reflected. On this particular morning, I caught wisps of fog wafting over the lake's surface in front of the dam.
