Looks like it's a good candidate for a rig and ring set in adjacent tree. Can be set and retrieved from ground, and you don't go for a ride cutting 12'logs. Spear cut the spar down so you don't have to tip the logs down.
Careful with this cut. Great for cookies or short logs, but if the piece is long, it tends to rotate backward as the butt slides away. The tip comes down over you and can hurt you badly.Ruel...I like the idea of spear cut pieces...let them slide off the spar, not have to tip over.
I meant for speedlining,
A single/ multiple-picket (t-posts, etc) anchor can put an anchor anywhere there's suitable ground, so you don't have to go to available trees.
I feel like there should be a dinosaur in the background of your pics. I get that feel.
Be aware of underground utilities with pound-in anchors.
