What is platteville limestone

The upper beds of the Platteville Formation in Kansas consist of dolomite, limestone, sandstone, and green shale, and in the basal part is a persistent dolomite 5 to 35 feet thick. Some sand generally occurs in the basal dolomite and disseminated in the shales and dolomites of the upper part.

The formation is restricted to the North Kansas basin. The Platteville is unconformable on the St. Peter Sandstone in northeastern Kansas Lee, et al. Map, no. Maximum known thickness of the formation in Kansas is feet in Brown County; it wedges out southward on the flanks of the Chautauqua arch and the Central Kansas uplift.

I have checked out all the photos on your blog by now and they really help, but I still have plenty of questions. One would be about the color of the Carimona. Written descriptions of this member describe it as pale yellow-brown. However, in the photos, it looks gray or yellowish gray.

I am trying to identify the stone on historic buildings constructed early St. Paul that are yellow limestone. I know they were constructed with local stone, and I am trying to make sure that I am correctly identifying the stone as Carimona. Would you say Carimona is generally pale yellow-brown? I would say pale yellowish gray, at least in the outcrops I am most familiar with.
