The basalt pillar faces Tech Breakdown You Can’t Miss
Basalt pillar faces are formed from the cooling of lava flows. The lava is made up of mostly basalt, a type of igneous rock that is rich in iron and magnesium. As the lava cools, it begins to contract. This contraction causes the lava to crack and form pillars with hexagonal or pentagonal cross-sections. The pillars can be up to 100 feet high and are often found in groups.
