>>2693307thanks for the bump anon
>>2691937I've checked this creek, and it does have an outcrop of the, the white bank is an indicator of the chalk up stream though that is not the creek I look for the boundary zone in but you're not far I'd say it's a few miles away. If your cheek looking you might find it lol. another thing is that sat images don't do justice to cuts done by streams, creeks, and rivers Thake this description from an excerpt of a paper describing exposures of Kef in the Dallas area, if you are able to find it I'll show you a pic of how steep the cut is compared to the sat pic. "Locality no. 16.-The Britton formation is exposed on the south bank of the Elm Fork of the Trinity River at the point where the railroad north out of Irving, Texas, crosses the river. The Dallas-Rhome highway crosses a short distance above this point. This locality was the site, of Horton's Mill where most of Hyatt's species were collected." note the "Dallas-Rhome" highway is now known as 114 and will be labeled so in maps as this paper was published in 1942. as you asked if you know the rough topography and general depth of bedrock the method of finding locations is great and is what I mainly use to find locations outside of scientific papers.
pic related is a rock lobster fossil, possibly Linuparus Grimmari, Eagle Ford group, Denon Co. Texas - Fossil Anon
