Discovering olivine in local basalt opened my eyes to city geology

I began to pause and really look at rocks during my regular walks instead of rushing past them. This simple shift meant checking textures and patterns with a hand lens I keep in my pocket. One evening, I found a dark rock near the curb that had tiny green crystals inside. A quick check confirmed it was basalt with olivine, something I never expected here. That moment felt like a personal victory, even though the rock was common. Now, I see geological stories in every crack and pebble around town. This habit has added a quiet joy to my daily routine.

I always dismissed city rocks as just plain granite or concrete until last year. Finding a piece of gneiss with really clear banding in a parking lot chip made me realize the whole foundation here is a mixed-up history book. It totally changed how I see the built environment.

Totally, those little finds can change how you see the whole city.

Yeah but honestly most of that stuff is just fill and asphalt. Walk around any new build site and it's all the same gravel mix from the same three pits. Kinda kills the magic for me.
