The following images of igneous rocks up close were taken in my yard near Bend, Oregon.

What’s an igneous rock? Geology.com describes them as being “formed from the solidification of molten rock material.” For example, granite, gabbro, basalt, scoria, and obsidian are all types of igneous rock.

You probably notice some of these rocks have round bubble-like holes in them. These “vesicles” form when gas is trapped within the melted rock at the time it cools and turns solid.

As you can see, there is a lot of variety in texture and color in the igneous rocks in my yard. The rocks pictured are small enough to fit in the palm of my hand – the perfect size for collecting. 😉
