Det cord is the only way to remove small trees. For big ones, a shaped
charge and a little C-4 works wonders. :)

Remind me to tell you about the time I removed a tree stump, and about
two tons of rock and earth plus about six neighboring trees, by using
slightly too much AN and diesel - it's a funny story.

Friend grew up in Kansas. Bounty of 5 cents a head for crows. So they
decide to dynamite a roost tree. Toooooo much dynamite! He said they
strapped 1/2 sticks of a full case (All the farmers had a case or two for
blowing stumps and rocks) all over the tree. About 1 am they set it off.
Looked like a nuclear explosion he states. They were caught and chastised
and they could find enough of 1 bird for a bounty. Huge cottonwood made
into toothpicks. As to shaped charges, my brother used them in the Seabees
and they later was an industrial engineer for a company manufacturing them.

There is a PTO driven attachment fits my Mercedes tractor, that turns
trees up to 6 inches into chips. Cuts a six foot swath. About a
hundred times faster than explosives. My brothers bulldozer,135hp, has
pushed over 18 inch or so trees. You can take down any tree with a
blade, by nibbling at the roots. Dynamite is older than the tractor,
and was once the only way to go for land clearing, but now it is
expensive. It has its place, huge boulders and bedrock. Only thing I
have personally blasted was snow. Very satisfactory avalanche, with no
skiers inside it.

Most blasting is done with ammonium nitrate mixed with 5% or so of
fuel oil. Saw a film of them shooting 800 tons, mining taconite in
Minnesota. Shot the charges in sequence to keep down the peak noise.

Explosions take the path of least resistance. They shoot in sequence to
provide that path. First sequence starts it. Second will blast the rock
to where the first was, and so on, and so on. It's more controlled and
you use less powder.

I think you misunderstand. These were half ton charges many feet
apart. Turned hundreds of acres into rubble. I don't know but I will
bet the endloaders and trucks are really big. The ships certainly are,
thousand footers that are too big to get out of the Lakes.
