What is normally considered the oldest mountain range in North America?

The AT is 2200 miles, 3500 Km. Not 200.

The Appalachian trail is 2189 miles long and goes from springer mountain in Georgia to katahdin mountain in Maine (Baxter Park) our son thru hiked it. Beautiful trail and experience. Many many great moments for him.

I cant believe I got this one wrong! And I live in the Blue Ridge! Cant see the forest for the trees, I guess.

I walked the entire width of the Appalachians' beautiful place

super interesting that the Appalachians and the Little Atlas were once connected

I believe the Blue Ridge mountains are a part of the Appalachian range. don't think this question was researched thoroughly.

Player Cosmo Chic, All the continents were connected. They formed one land mass. Pangea.

Player #34344403, The Himalayans are still growing because the plate that India is on is still pushing north into Asia.

Nova, The pronunciation depends where you live. We who live in Pennsylvania pronounce it differently than those who live south of the Mason-Dixon. Regional dialects are interesting.

Am I the only one who pronounces it APP-el-AY-shun?

I got thiswrong, all the while i thought it's John Denver's blue ridge mountain .....

Player #34344403, Agreed. Laurentian rocks are found to pre-date the Cambrian Explosion (~530 mya) and the range is associated with the Grenville Orogeny (mountain-building), somewhere around a billion years ago, during the formation of Rodinia, a supercontinent PREDATING Pangaea. Some believe the Laurentians were once higher than the Himalayan mountains. The Appalachian chain was formed during five collisions with what is today Africa sometime between 325 and 260 million years before present.

Me, Appalachian Trail. what the question is about.

LyingMedusa78458, 3500km!!! Hot Diggity dang that's loooong!!!! I am used to speaking of long distances where I live and I knew the AT is long but, Heck! I never knew it is THAT LOOOONG. No wonder so many people go missing there. Thanks for giving the metric too!!

Mari, I'va always thought the Appalachians and the Alps were one chain back when there wasn't any pacific ocean.

Player smartrican, you mean length?

Wrong! The Laurentians Mountains are the oldest. they are part of Canadian Shield formed during the precambrian period 540millions ago. Think about the Himalayas are the youngest and highest has they have not been yet eroded by time, glaciers and other factors. Look up at the heights of the mountains in the Laurentian Mountains like Mount Tremblant it is only 2871ft, a speed bump for the wind.

Laurentides the oldest

Great info. Thanks.

Player Cosmo Chic, all continents at one time were connected and they will be again if the Earth stays around long enough. of course that's mostly just a theory.

Gary, they are part of it they are considered their own set. you are 100% right.

Bill D Maryland, They were referring to a walking trail being 200 miles long.

Gary, I thought the same thing.

I dummly thought most of the North American mountains were formed the same time! And because of that, I was also thinking this was a tricky question. Which mountain range was discovered first? huh? huh? lol.

North America ?

isn't Alaska part of both America ?

Provide Very pretty scenery
