Check out this spectacular basaltic feeder dike with geology professor Shawn Willsey. This impressive geologic feature was the conduit that delivered lava to a surface eruption about 800 years ago, part of a series of eruptions on the Reykjanes peninsula known as the Reykjanes Fires. Learn how these dikes formed and then go up close to see how dikes affect the rocks they intrude.
