The Olympic Mountains, located in northwestern Washington state, present an imposing landscape dominated by snow-capped peaks and deep river valleys. This region, known for its complex geology and rich biodiversity, offers an outstanding example of how geomorphological processes, such as glacial and fluvial erosion, shape the Earth's surface over millions of years.

The formation of these mountains is the result of the interaction of tectonic plates, which uplifted the Earth's crust, and the subsequent action of glaciers during ice ages. These glaciers carved out U-shaped valleys and left behind the characteristic sharp peaks. Subsequently, rivers have continued the erosive work, deepening the valleys and transporting sediments, which contributes to the constant reshaping of the landscape. This continuous process of uplift and erosion is fundamental to understanding the dynamics of mountain ranges worldwide.
