A fence was put up around the Black Hawk statue Friday at Lowden State Park in Oregon as restoration work by Conservation of Sculpture & Objects Studio Inc. in Forest Park began on the base of the 103-year-old monument. Restoration work will continue throughout the summer. Testing and evaluations done recently show that three areas of the statue are significantly deteriorated and in dire need of repairs. Those include the folded arms, especially the elbows and underneath the arms; the middle of the robe; and the vertical fold in the robe from armpit to toe. Chunks of concrete have fallen from the areas, and others are loose and ready to fall.
