The thought of having to dig out the stump on one of my ancient Ponderosa pines - makes my knees weak & my head spin. I only cut the ones that have become infected with Pine Bark beetle. The entire tree is then burned.
This is an eight foot chunk out of one of my pines. This chunk was twenty feet up the trunk. The stump was 41" on the butt. It took Mother Nature eleven years to rot out the stump.

If I too awful many like your pictures show - I'd consider dynamite. But then - I guess not. I can see houses in the background. Not a really great idea when you have neighbors.
