Igneous Rocks at Eldorado Canyon

When searching for igneous rocks, I found that Eldorado Canyon State Park is a good place to go. Many of the large rocks are light grey in color and jut out at odd shapes and formations. This is indicative of intrusive rocks. I would call these massive intrusive rocks because they are mostly in blob form verses the tabular or flat table-like shape. These rocks seemed to have been formed from magma being forced upwards between cracks in the Earth’s crust. Most of the rocks I observed were granite, and with granite’s porphyritic texture these rocks and the minerals inside them cooled slowly and at different speeds. The feldspar that was in most of these rocks was a light grey color, but I did find some that had the salmon pink color. There were a few rocks that I noticed had very large deposits of white feldspar (which I included a photo of)

Based on my observations, a large majority of the igneous rocks in Eldorado Canyon are felsic. I believe these igneous formations are so prominent because they are concordant rocks that have interjected into sedimentary formations that have since eroded and left only the igneous rock.
