An Out-of-This-World Landscape: Interview with a Craters of the Moon Geologist
In the high desert of southern Idaho lies a vast, stark landscape of black basalt, deep craters, and jagged lava flows. Craters of the Moon National Monument & Preserve looks less like the American West and more like the surface of another world. To understand how this bizarre topography formed and why it attracted the attention of NASA, we spoke with Dr. Elena Vance, a research geologist who has spent decades studying Idaho's volcanic history.
Science Weekly: Dr. Vance, thank you for joining us. To start, how did Craters of the Moon get its name, and is it actually related to the moon?
Dr. Elena Vance: Thank you for having me! The area received its name because early explorers and geologists felt the vast fields of dark, barren lava resembled the lunar surface. While it wasn't created by meteor impacts like the actual moon's craters, the volcanic features here are structurally very similar to the basaltic plains found on the moon, which are called maria. It is a wonderfully accurate nickname for a place that feels entirely alien.
Science Weekly: Most people associate volcanoes with towering peaks like Mount Rainier or Mount St. Helens. How did the volcanic activity here differ from those famous volcanoes?
- Basalt:
- A dark, dense volcanic rock formed from the rapid cooling of basaltic lava.
- Fissure:
- A long, narrow crack or opening in the Earth's crust through which lava can erupt.
- Terrestrial Analog:
- An area on Earth that shares geological or environmental characteristics with other celestial bodies.
- Extremophiles:
- Microscopic organisms that survive and thrive in extreme, harsh, or nutrient-poor environments.
