Hello! My name is Kira Harris, and I am a senior Earth Systems Science major. I love learning about how different pieces of Earth’s processes intertwine. I am also an Education and Outreach Intern at the Byrd Polar and Climate Research Center here at OSU, which is the coolest (!) place to work on campus. I plan to continue on to graduate school, and I hope to one day work with tree rings and/or ice cores!

My header photo is a photo I took at John Bryan State Park in Yellow Springs, OH during a Sedimentology and Stratigraphy field trip last fall. You can see the mosses hanging above a creek, but what you can’t see is the super cool substrate: an inorganic, chemical sedimentary rock called travertine. Above the mosses there is a natural spring that flows over a ledge, falling into the Little Miami River. The geology of southwestern Ohio is predominantly limestone, which is made of calcium carbonate (CaCO3). As groundwater flows through the soluable limestone it picks up that CaCO3 and it gets precipitated out as it flows from the spring opening to the river, forming a rock! (Think of stalagmites and stalactites, the build up of minerals from the constant dripping of water!)
