Long-lost fragment of Stonehenge reveals rock grains dating to nearly 2 billion years ago

"I've wondered if the builders of Stonehenge could tell something about the stone properties, and not only chose the closest, biggest boulders, but also the ones that were most likely to stand the test of time," Nash said. "

It would be interesting to know what other rock options the Stonehenge builders knew about, and where they are located...closer or not. It might be that this was their only choice?

This link and quote may help you 'Some of the volcanic bluestones in the inner ring of Stonehenge officially match an outcrop in Wales that's 160 miles (257 kilometers) from the world-famous site '

 
Well, that seems to indicate that there were several choices for the Stonehenge builders. But the Ngeo headline is an overstatement if bluestones are only in the inner ring. SOME Stonehenge Stones were moved would be better?

However it answers your question "It might be that this was their only choice? " - Unlikely their only choice if they used some stones from 160 miles away and not all.
