Here's a breakdown of the age of the rocks in the Adirondacks:
* The oldest rocks: Found in the central Adirondacks, these are igneous and metamorphic rocks formed around 1.1 billion years ago. This makes them some of the oldest rocks in North America.
* Younger rocks: These include sedimentary rocks deposited around 600 million years ago and are found in the western and eastern portions of the mountains.
* Metamorphism and Uplift: Around 1.2 billion years ago, the rocks were uplifted and metamorphosed, creating the mountains we see today.
So, while the specific ages vary within the Adirondack Mountains, the bedrock is generally considered to be Precambrian, making it incredibly ancient!
