Week 2: Igneous Rocks by Mr. Martinez



    As my wife and I visited the Denali National Park and Preserve in Alaska, we came across the most astonishing view and focal point of the park, Mt. McKinley. Approximately fifty-six million years ago when molten magma slowly cooled and solidified deep beneath central Alaska it created a beautiful plutonic rock, made up mainly of granite, known as Mt. McKinley. As the surrounding mountains erode more quickly through the years of the freezing and thawing of snow or grinding and scraping of glaciers, Mt. McKinley is pushed upward as it remains like a resistant sentinel. Also found in the park while exploring were red, yellow, and brown basalts, rhyolites, and andesites formed from rapidly cooling lava that can be seen along the park roads. If you find yourself venturing in Alaska, I highly recommend taking on the spectacular experience of the Denali National Park and Preserve.
