Here are all the clues you should need to identify this mystery spot:

Along the shore
There are seekers of ore
In an ancient keep, high above a vast deep.
My mind’s eye saw them, though they’re not real men
As we passed them once, and soon once again.

Bonus clue, no extra charge: Some are round and hollow, their glitter hidden.

Remember that this is a two-part question. To get full credit you must identify the specific physical or cultural feature as well as the national park in which it is located. Good Luck!

The answer and a list of readers submitting correct answers will be posted in tomorrow's Traveler.
