Riverside-Thomas Cemetery is located six miles west of Blackfoot on Highway 39. Alphes Parsons donated five acres of land to be used as a cemetery. His father, James Parsons, had died in 1887 and was the first person to be buried there. In 1897 an additional five acres was purchased from Mr. Parsons for $10 an acre. In 1984 five additional acres was purchased from Jennie Williams for $2,000 an acre. The cemetery has changed from an area covered with sagebrush, weeds and rocks to a beautiful garden due to the efforts of many local residents, as well as some W.P.A. workers supplied by the government.
