Chalk used as construction material at Gavins Point Dam
Gavins Point Dam, near Yankton, SD includes embankment containing 11, 000,000 cu yd of Niobrara chalk, found in quantity in this area; formation is lead gray, argillaceous (clayey) chalk and chalky shale of sedimentary origin derived chiefly from shells or marine organisms; dry weight varies from 80 to 115 lb per cu ft; excavation for both powerhouse and spillway cuts entirely through Niobrara chalk formation and into Carlile shale formation.
