▲ 28 ▼ Morning Rio Grande Pumice Haul (slrpnk.net) submitted 4 months ago by nocturne@slrpnk.net to c/cool_rocks@lemmy.today 4 comments fedilink hide all child comments Since the river is totally dry, I decided to take the dogs on their morning hike in the riverbed. I was surprised how much pumice I kept finding. I started to leave the small pieces, looking only for larger pieces. Bonus, some Asian clam shells, and this pretty shiny red-brown rock.
