The volcano was dormant for hundreds of years until in 1968 it erupted unexpectedly, destroying the small town of Tabacon.

U.S. Geological Survey says there are at least 169 active volcanoes in the United States. Lava Rock technically is molten or “liquid” rock that come out of an erupting volcano at temperature of 1,300—2,000 degrees. When lava cools it forms igneous rock. Depending where and how long it cools it can form different types of rock, including Basalt, Obsidian, Volcanic Rock and many others.
Volcanic Lava Rock?is very porous and weighs less than half that of other landscape materials making it easy to transport and spread. Lava Rock insulates the soil from heat and cold. Studies show that lava rock is more effective in retaining moisture in topsoil, than wood mulch products. It helps better regulate moisture in the ground and will not rot, decay or be subject to color fade like wood mulches, making it a permanent mulch replacement.
