Lava is molten (or melted) rock that comes directly from a volcanic eruption. When it first flows from a volcano, it can be as hot as 2,200 degrees Fahrenheit. It can flow great distances before cooling and solidifying into igneous rock. Volcanoes are found all over the world, including Northern California, Hawaii, Alaska, and Nevada. Lava rock is different at each volcanic site.

These specimens are great to add to your collection or can even be starters to a new hobby of collecting volcanic rock from around the world!
