World's Oldest Rock.

World's Oldest Rock

This wasn't really what we expected. Honestly, it's not quite up to what I would expect to find from what most people share on this site. We thought we would see one rock claiming that it's the oldest. At first, when we pulled up, it was hard to tell which of the rocks was the one. After reading the marker, it's "some of" the world's oldest rocks.

[Sarah, 06/16/2020]

We agree that the plural use of "rock" is misleading, but the historical marker claim of "World's Oldest Rock" asserts craggy self-confidence. And how often do we get the chance to touch something 3.8 billion years old?
