So i've been looking at these rocks, i've dubbed them QD's mounds.
So far as I can tell they are up in the Grizzlies somewhere east of Valentine, maybe up near Iron Cloud. They are different from this rock (left side) which I was also looking at.
Which is somewhere in the centre-east of the map, not quite sure where but it's seen quite a lot. Then I got to looking at that river, meanders north east not really matching anything we have on the map, doesn't look like Roanoke Ridge area to me. Now, looking at the border between The Heartlands and Scarlett Meadows there's a place called Dewberry Creek which would suggest a river running through it. The border runs at a 45 degree angle like the river, so my guess is it would be there. Any thoughts?
