Found this one last summer. I think it is Niobrara Chert. Hopefully some of the Nebraska folks can help me on this one.

A hero is no braver than an ordinary man, but he is brave five minutes longer.

Calling the material Niobrara because it is from the Niobrara formation can be confusing to some because that particular formation covers a huge area of the Plains (parts of seven states).
Some archaeological publications refer to it as Smoky Hill chert/jasper and some refer to it as Niobrara which also can be very confusing to those not familiar with this particular lithic.
It was a Kansas archaeologist who started using the term Niobrara jasper over twenty years ago in his publications but he now agrees that was not a good idea. Interestingly, in his latest publication (2010) he has reverted back to using the more appropriate scientific name, Smoky Hill jasper. SH
You have to love those materials found in Nebraska...thanks for the info smokeyhill, by the way how do you pronounce "Niobrara" ?
Broken but some characteristics found on Folsom "ultrathins"--very thin and flakes are diving in to thin the center...looks like a P-wood to me. I don't know the exact provinance. The Graham family farm? Nebraska - 1950's
Good ole Smoky Hill Jasper. Find quite a bit of it here in S.W. Ks. Nice piece.
Mike this should get you in the ball park: Ni-o-brar-a or nigh-uh-brair-uh
