LOTR: Why Didn't Frodo Bury The Ring Deep Underground?

gamerant.com:

The one Ring of Power is Sauron’s master weapon, which can be used to dominate and control almost any character in theLord of the Rings. It has an allure unlike anything else in Middle Earth, to the point where entire races of peoples have fought over and died for it.

The Ring has an interesting journey from Isildur, the man who cut it from Sauron’s finger, down the river Anduin, into the possession of Gollum. It is then picked up by Bilbo Baggins in the goblin tunnels during the quest for Erebor, and taken back to The Shire where it comes to rest in the hands of Frodo. But when the enemy discovers its whereabouts, and the council of Elrond meets in Rivendell to decide the ring’s fate, why don’t they bury it deep underground so that Sauron cannot claim it? In essence, the reason lies in the fact that there is no place on the whole of Middle Earth where the Dark Lord cannot find it.

In fact, many such suggestions come up at the council to hide the ring from Sauron. People suggest tossing the ring into the depths of the ocean, or transporting it to another place like Valinor, where it would be out of reach. But for a Dark Lord who will stop at nothing to retrieve the object of his power, it would only be delaying the inevitable. It would simply postpone the complete domination of the world, rather than preventing it entirely, which could be done by destroying the Ring once and for all. That is why the decision is made for the Ring to be taken back to the fires of Mount Doom where it was forged, the only place that it can be permanently removed.

Burying the ring would simply be a temporary solution to a problem that could destroy Middle Earth
