Pikes Peak - One Billion Year old granite / Universe is 14 billion years old

Post by jibler »

that's some heady rock there


I feel we need more loose wacky mtn fact discussion


I was reading the CO roadside geology book - it said that Pettingell Peak was the only peak to break above the glacial layers last Ice Age?

and did you know about the Piedmont ? Were you calling it that?

We're fortunate to have access to the mountains of Colorado. They're not to be taken for granite.

The granite and quartzite in the Needle/Grenadier range is ~1.5 billion year old precambrian rock, I believe

As I recall from geology class, Australia has some rocks that are about as old as the Earth, some 3.8 billion years old. There are rocks in Canada that are over 4 billion years old.
