On Wednesday, September 13, 2006 through Friday, September 15, 2006, forestry scientists from Michigan Technological University and their cooperators conducted decay detection tests on 10 red pines supporting a ropes course in the United States Forest Service (USFS) Nesbit Lake Camp in Sidnaw, Michigan. The Copper County Intermediate School District (CCISD), Hancock, Michigan, cooperated with the USFS in providing the recreational ropes course for use by students and other groups. The purpose of the project, in addition to detecting decay, was to research the reliability of detection protocols and to compare results of the various equipment used.
