Geology tea, served hot
The Scottish Highlands, the Appalachians, Atlas are the same mountain range
Internet melts: Highlands, Appalachia & Atlas were once one—map sparks chaos
TLDR: Scientists say Scotland’s Highlands, the Appalachians, and Morocco’s Atlas were once linked as one range on supercontinent Pangaea. Comments erupted over a broad map, corrected the Ouachitas claim, asked why the Atlas stay tall and where the Himalayas fit, and dropped a hiking link—geology drama that makes Earth feel connected.
Vivid Maps dropped a geological bombshell: the Scottish Highlands, the Appalachians, and Morocco’s Atlas were once one mega-mountain, the Central Pangean Mountains. The crowd went full “long‑lost cousins” energy. One user confessed, “Didn’t know about the Atlas,” while flexing the Scotland–Nova Scotia connection, and the wow-factor spread fast.
Then came the map wars. Skeptics like tengwar2 squinted at the graphic: it blankets most of the UK—“including the famously flat Lincolnshire fens.” Commenters piled on the corrections: Bob Costas dunked, “Ouachitas is incorrect,” and Jenn chimed in that the map doesn’t back it. Cue questions: trgn wondered why the Atlas “remain very high” if the old range eroded; brcmthrowaway asked where the Himalayas fit. Quick primer: those ancient peaks formed when big land masses slammed together; wind and rain shaved them down over ages; the Atlas got a fresh lift from modern plate shoves; the Himalayas are a younger collision story.
Hikers added chaos with the bucket‑list International Appalachian Trail, joking you could walk “from Glasgow to Morocco.” Memes crowned the saga “Euro-Appalachia,” while locals joked the fens just got promoted to mountains. Verdict: awe, nitpicks, and a continent-spanning family reunion vibe. And yes, the title sparked more heat than magma.
Key Points
- •The Central Pangean Mountains formed from the collision of Laurussia and Gondwana during Pangaea’s assembly.
- •At their early Permian peak, the range reached elevations comparable to today’s Himalayas.
- •The Scottish Highlands, Appalachians, Ouachita Mountains, and Morocco’s Anti‑Atlas were once connected within this ancient chain.
- •Permian physical weathering lowered peaks and created deep intermontane plains; by the Middle Triassic, the mountains were substantially reduced.
- •By the early Jurassic (~200 million years ago), the Pangean chain in Western Europe largely disappeared, leaving isolated highlands separated by marine basins.
