First beautiful Fall day, a big crop of dubious choices.

Single carabiner connecting the webbing, and the purple rope is 8mm at most

Unnecessary carabiner, not much tail on 8mm tensionless anchor.

There was plenty of rope to just tie around the tree. Introducing the 2 extra links in the chain increases risk.

Single carabiner connecting to what looks like 8mm or thinner rope.

How to cut your rope.

This doesn't show you how really sharp that edge is.

You don't have to wrap the tree up like a mummy, 3 turns are enough.

It's probably a rappel rope but it's still a terrible idea.

The newly popular loose rock.

This loose block is poised to drop on the climbers.

Another flying double anchor.

Single strand webbing, carabiner gate towards the rock, so it could be forced open, anchor angle of about 120 degrees to maximize force on all the points.

Another carabiner facing the rock.

Is 9MM anchor line safe? Yes. Is it smart? No. It will stretch twice as much as 10mm rope, cutting, abrading, and wearing out much faster. Here they had plenty of rope but came up about 6 inches short, even the clever rope condom won't prevent friction of the climbing rope.

The instructor said,"There's safe, and then there's REALLY safe."

Sure, anchor 10 feet up the tree.

This block is not attached, so wrapping it half way up is way worse than at the bottom.

See the slack, the tiny tree at right is the only anchor actually working.

Since it is working, we know it is a tensionless anchor.

The anchor greater than 90 degrees putting more stress on each point.

Boat Rope!

You just don't see this stuff much anymore.
