Sica Hollow State Park (also Sieche Hollow State Park) is a state park of South Dakota, USA. It was named Sica, (pronounced See-Chah) a Dakota word for bad or evil, due to the iron-red tinted water which was seen as blood by the Dakota tribe in the area. Sica Hollow once protected many peaceful Indian camps. Its trees blocked the North Wind. But, a stranger named Hand came. He scared the females of the tribe. The old men said he would leave come spring.
