The oldest known volcanic basalt plug in the world, makes a great place to view sunrise or sunset in the area. It’s located 15 minutes from Sapphire.
A volcanic plug, also called a volcanic neck or lava neck, is a volcanic object created when magma hardens within a vent on an active volcano. If a plug is preserved, erosion may remove the surrounding rock while the erosion-resistant plug remains, producing a distinctive upstanding landform.
