Beacon rock is not a volcano, but rather is the basaltic andesite volcanic neck or plug (core) of an ancient volcano, the softer outside of which was eroded by the Missoula Floods.
Igneous rock, such as basalt or andesite, results from the cooling of lava from a volcano.
A volcano has magma,the molten rock that comes from the core of the earth.
Rock that is ejected from a volcano and cools is called volcanic rock or lava rock. This type of rock typically has a fine-grained texture due to rapid cooling.
