The land owner first observed the feature July 2007 in a native grass hayland. The feature’s shape was circular and was six feet in diameter and 30 feet deep. The land owner backfilled the feature October 2007 and submitted a plugging report to the Kansas Department of Health and Environment (KDHE), Appendix - Exhibit ‘C’. After a cutting of native grass in the summer 2008, the land owner observed the backfill had settled about three feet. Additionally, the land owner noted that the backfill material appeared to be churned up3. The land owner contacted Sandy Koontz, Butler County Conservation District (BCCD), about the feature and a field inspection was conducted by BCCD staff July 23, 2008, Appendix - Images 1 and 2.
