New Pattern: Basalt Columns!

Flood basalts (or "oops, all lava" events) create regular structures - and basalt in particular loves to make columns. But not just columns - pillow basalts, joints, pelagonite, entablature, breccia and more are all part of a typical basalt flow. So this new pattern features the common pieces of a basalt flow - and hides a few fossils and archeological elements from the Columbia River Basalts in its midst!
