Talk:Valentine Formation

Please, add type location photo
I have many pictures of the opaline sandstone throughout west-central Kansas. However, the Valentine classification is no longer formal in Kansas, even if it is still an obvious characteristic feature, especially in inverted topologies. Somebody, for the infobox, please, upload a photo of the opaline sandstone outcrop near Valentine, Nebraska.
