Talk:Halgaito Formation

Mexican Hat?
Is Mexican Hat, in Utah, an example of this? If so, an number of images in the commons would work. I'm just not clear if the rock is connected to Halgaito Shale because it was colored by the shale or it is of the Halgaito shale.- Trilotat (talk) 23:22, 30 September 2018 (UTC)
