There's a special type of lava rock that can be found throughout the Bruneau Desert lands of southern Idaho. Rhyolite is composed of quartz, feldspar, and biotite, according to websites that specialize in petrology. They form from cooled lava, and over time, can produce some incredible formations that can be found within the rock. These rocks are also referred to as Thunder Eggs.
