Here's a few more pictures of that "spear tip", I think anyway.
Also, a couple of views from on top of that crazy river rock mountain. It's nuts how far up I am from ground level and how long this thing is. The first picture is a view from one end and the second picture is from the other end.
Actually takes a couple minutes to walk from one to the other! In both pictures you can see the ramp where the bulldozer gets up and down from. Plus here and there how high the sides are. At any point from the base it takes me about a minute or so to ascend!
I've only began, on both sides of the road. In the second pictures., you can see the gravel mountain that is across the road top right.
