Coso Hot Springs deposit, Coso Hot Springs, Coso District (New Coso District), Inyo Co., California, USA 9.1 x 6.4 x 6.0 cm. A specimen otherwise known as volcanic glass, from California. It almost looks like man-made slag but is of course natural volcanic igneous rock - great for demonstrating to kiddies! Small cristobalite crystals are also present inside the obsidian bubbles. |
