Description
The Cottage Anticline was mapped from borehole data on the Herrin Coal Member. These data show a small area of closure in the northwest quarter of Section 15. The north limb dips about 100 feet per mile (1°), and the steeper south limb is truncated by the master fault of the Cottage Grove Fault System, which shows about 70 feet (21 m) of downthrow to the south.
