Kalona Clay Pit near Kalona, Iowa

Recommended Posts

"Maple Mill Formation near Kalona, Iowa." came up in a topic about Devonian Shark's teeth. It is a micro matrix type of material that I am interested in collecting next summer. I hunt just north of Kalona anyways!!! Has anyone ever collected this matrix or knows the location of the Kalona Clay Pit?? All of my research reveals only vague references and looking at google maps shows little exposure of rock around Kalona. All help would be greatly appreciated.

 

Thanks,

Mike

I can find four references for the Kalona Clay Pit. They are:

multielement genus of Late Devonian conodont.

Maple Mill Shale Formation (Upper Devonian) of southeastern 

Iowa, USA. Micropaleontology, 45(3), pp.304-318.

 

Olempska and Chauffe (1999) states:

 

"The Kalona Clay Pit was opened by the Farley Brothers Brick

Company early in the twentieth century as a source of clay for

making building and paving bricks. After a short period of operation,

the pit was abandoned. In 1978 the exposed Maple Mill

section in the Kalona Clay Pit was approximately 4.5 meters

high, eight meters long and capped by a .75 meter exposure of

English River Siltstone. The channel of a small unnamed, 

intermittent tributary of the English River formed the base of the

outcrop. The lower contact of the formation was not visible at

this location."

 

Olempska and Chauffe (1999) and the other papers, should

provide the locality information that you want.

 

Yours,
