The photo is from Google Earth and it is of the composting area of the Creek Side Mushroom Co. now defunct. The company was started by the Butler County Mushroom Farms in 1937 and provided 90% of the worlds mushrooms. You probably have seen them on the grocers shelves under the Moonlight Mushrooms brand. The mushroom growing area used 150 miles of abandoned limestone tunnels encompassing 800 acres beneath the surface with production capability of 60 million pounds annually. Creek Side Mushroom Co. downsized the operation and recently closed its doors.
What looks like two sets of tire marks are the remains of the last four compost piles. They measure 330’ long and were 16’ wide and 16’ high. At the peak of business there were 8-10 rows of compost on that pad.
