The Journey of a Grain of Sand

Some of the sand grains in this story are made of zircon crystals over four billion years old — older than almost anything else on Earth's surface, and old enough to have witnessed the planet when it barely resembled the one we know. Tonight, I'm following one grain of sand from a Rocky Mountain peak to the bottom of the sea it's been slowly, patiently returning to for millions of years. ⏳ 100% science-based. No fiction, nothing added beyond real, verifiable geology. ✅ Got a story you'd like me to tell next? Leave it in the comments. 📩 Hi!
