Geo Beckly: Rocks on the Road
Geologist and naturalist Becky Nesel shows how rocks shape plants, hot springs and even New York's brownstones, mostly from road trips.
What it is
@geobeckly is the TikTok of Becky Nesel, a New York geologist and science communicator. Her profile lists her as a naturalist with a B.S. in geology, and an interview with outdoor brand Toad&Co says she worked briefly as a geologist in construction and engineering before moving into science communication, where she hosts, writes and produces the show New York Rocks with Geo Beck. When we checked, the account had about 70,000 followers and a million likes.
Videos are in English and mostly come from trips: Becky goes somewhere with interesting geology and explains what you're looking at and why it's there.
Why we picked it
She treats geology as part of a bigger picture rather than a list of rock names. Her autumn 2026 video from the Mono Basin in California's Eastern Sierra is about how geology and ecology intertwine there, with endemic plants growing on unusual ground found nowhere else. Alongside it is a reflective video about her first fully solo road trip through the same region.
The archive has a great run from Vancouver Island. Pillow basalt near the town of Sooke, which she calls the world's uncomfiest pillows: lava that erupted underwater around 50 million years ago. A hot spring that exists because of a fault. Concretions that look a lot like fossilised dinosaur eggs but aren't. And a lovely explanation of an unconformity: like reading a book, turning a page and suddenly finding yourself in a completely different part of the plot, several chapters missing.
Her earliest videos are urban geology: what New York's famous brownstones are made of and why the stone fails over time. There's simply beautiful material too, like the monarch butterfly migration in Mexico.
One honest caveat: Becky posts irregularly. After summer 2025 there was a long gap, and new videos started appearing again in autumn 2026.
Where to start
- The Mono Basin video on geology and endemic plants.
- Pillow basalt at Sooke on Vancouver Island.
- The unconformity-as-a-book explanation.
- "Is it a fossilized dinosaur egg?" on concretions.
- The early brownstone videos, if you know New York.
Who it's for
Road-trippers and national park fans who want to understand the views. New Yorkers who've never wondered what their neighbourhood is built from. Geology students looking for a model of how to talk about the field without jargon. Anyone who likes calm, unhurried nature videos.
Quick answers
How often does she post? Irregularly: after a break from summer 2025, new videos appeared in September and October 2026.
Who is Becky Nesel? A New York-based geologist and science communicator who hosts New York Rocks with Geo Beck.
Is it only geology? Mostly, with nature and travel woven in, from monarch butterflies to solo road trips.
