DO NOT UNTIE ANY KNOTS ! JUST PULL ON ONE SIDE AND THE CORD WILL LOWER THE CONTAINER.
Is it a bird ? Is it a plane ?
No -- it's a geocache !
And while it is not within reach, you do not have to be a Superhero to get it, because there is
NO TREE CLIMBING REQUIRED
You will need to go about 8 feet up the hill which is loose rock and dirt; look low on the trees for how to get the container down before going up the hill to make sure you are at the correct tree (there is a spoiler photo attached of what to look for).
Congratulations to hartsale for being FTF !
