The Silurian sandstones of northeastern Ohio, informally termed white "Clinton," red "Clinton," and stray "Clinton," in ascending order, have been described by various investigators as belonging to a major Silurian delta complex sourced from an easterly direction. Detailed study of geophysical logs of a limited area in Summit and Portage Counties supports this interpretation. Isopach maps, sand thickness maps, and sandstone-shale ratio maps show a pattern of probable deltaic distributary streams flowing generally from east to west, bifurcating at places to probable crevasse splays, and terminating westerly in nearshore beach and marine bar sands. The units are probably marine regressive. In ascending order, the white Clinton represents partial bars, beaches, and delta fro t; the red Clinton represents poorly drained swamp and/or upper delta or fluvial environments; and the stray Clinton may be marine transgressive representing environments similar to the white Clinton.
