St. Peter Sandstone Thickness
<DIV STYLE="text-align:Left;"><P STYLE="font-size:16ptmargin:7 0 7 0;"><SPAN><SPAN>We chose to use the map of Collinson and others (1988) because it shows thickness at 50 (rather than 100) ft intervals. Kreutzfeld (1982) pointed out that the thickness of the St. Peter Sandstone is much more variable than the formation-thickness map indicates. The variation in thickness is due to postdepositional erosion and its highly irregular lower boundary. The base of the St. Peter Sandstone is a major regional unconformity (Collinson and others, 1988; Young, 1992b). </SPAN></SPAN></P><DIV><P><SPAN /></P></DIV></DIV>
