Yeah, that's fair. The opening in (B) could certainly stand on its own as a complete sentence. Fortunately, as you noted, the "where" incorrectly modifies "New Mexico," so we've got a modifier error we can use to eliminate the option.

Exactly. The site may have been discovered recently, but that doesn't mean that the site was used recently. Recently discovered bones could have been gnawed on thousands of years ago, or a recently discovered sword could have been used in battle hundreds of years ago. In essence, the "recently discovered" is a modifier describing the site, not setting the timeframe for the action of the sentence.
In this case, the recently discovered site was used by the Anasazi in the past to establish the positions of the sun and the moon over 19-year-cycles.
I hope that clears things up a bit!

It does help, GMATNinja! Thank you so much for the clarification! Yes, I might have inadvertently stretched the recently discovered modifier to the time when patterns were employed.
I understand it now: The sentence ONLY says that the patterns were employed at the recently discovered site, not WHEN the patterns were employed. To find out "WHEN", the 19-year cycle is mentioned in the latter part, which clarifies that the Anasazi were the only ones who could have employed the patterns! That's why C is correct!

A site once used as an observatory by the Anasazi, ancient pueblo dwellers of New Mexico, has been recently discovered where patterns of light and shadow were employed to establish the precise limits of the positions of the Sun and Moon over a nineteen-year cycle.
(A) A site once used as an observatory by the Anasazi, ancient pueblo dwellers of New Mexico, has been recently discovered where patterns of light and shadow were employed to establish the precise limits of the positions of the Sun and Moon over a nineteen-year cycle. -> Is ancient pueblo a site once used....Incorrect.
(B) A recently discovered site was once used as an observatory by the Anasazi, ancient pueblo dwellers of New Mexico, where patterns of light and shadow were employed to establish the precise limits of the positions of the Sun and Moon over a nineteen-year cycle. -> Same as A. Incorrect.
(C) At a recently discovered site once used as an observatory by the Anasazi, ancient pueblo dwellers of New Mexico, patterns of light and shadow were employed to establish the precise limits of the positions of the Sun and Moon over a nineteen-year cycle. -> Now the first part is changed, it starts with a preposition and meaning wise sentence is better too. Let's keep it.
(D) Patterns of light and shadow were employed to establish the precise limits of the positions of the Sun and Moon over a nineteen-year cycle at a site that was recently discovered and was once used by the Anasazi, ancient pueblo dwellers of New Mexico. -> "cycle at a site" is incorrect. It changed the intended meaning.
(E) Patterns of light and shadow were employed to establish the precise limits of the positions of the Sun and Moon over a nineteen-year cycle at a recently discovered place that the Anasazi, ancient pueblo dwellers of New Mexico, once used the site as an observatory. -> Modifier error, "discovered place that the Anasazi, ancient pueblo dwellers of New Mexico".
So, I think C.
