Hello I found this piece of sandstone along the Athabasca river just south of Fort McMurray, Alberta, Canada. Since it’s sandstone I’m assuming it came from either the Mcmurray (late barremian or early Aptian) or Grandrapids (Albian) formation although my geology skills are not great. I tried to do some googling on what it could be but I found no results since I couldn’t be specific enough since I don’t really know what I’m doing. Any ideas?
I attached an image of the location for fun that I took a while before I found the rock. I found it to the right of the creek
thanks
