in washington state
Hello everyone. My name is [Your Name], and I am so excited to be talking to you all today about the tremendous beauty of Washington State. Specifically, I’m going to be discussing Mount St. Helens and Mount Rainier – two remarkable volcanoes that have captured the hearts of hikers, skiers and nature lovers alike for decades. From their towering heights to their fascinating history, these majestic mountains are truly something special to behold – and I’m here to share my personal experiences with them! So get ready for a journey through the wonders of the Pacific Northwest alongside me!

Geology and Erosion of Mt. St. Helens

Mt. St. Helens is a stratovolcano located in southwestern Washington and is part of the Cascade Mountains, along with Mt Rainier which lies to the north of it. It’s location within an area known as “The Ring Of Fire” has made it susceptible to regular seismic activity for millennia, resulting in frequent eruptions throughout its history.

Mt St Helens stands more than 8,000 ft above sea level due to thousands of years worth of tectonic uplift combined with multiple lava flows that have built up its peak over time.

Erosion from several active glaciers on the mountain has had a large impact on the geologic make-up of Mt St Helens over time as well; these glaciers have removed large amounts material from around its cone shaped summit through their continual movement downslope towards lower elevations.

  • This process results in sharp ridges called aretes which can be seen when viewing aerial images.
  • It’s also created impressive faces such as Loowit Falls and Takhlakh Lake which are some unique features that define this particular mountain.
