The Ruth Mountain is a mountain in the Skagit Range two miles (3.2 km) south of Hannegan Pass in the North Cascades in the State of Washington . The mountain was named in honor of Ruth Cleveland, daughter of US President Grover Cleveland . Ruth Mountain lies on the border between the North Cascades National Park and the Mount Baker Wilderness (which is part of the Mount Baker-Snoqualmie National Forest ). The summit offers views of Mount Shuksan , East Nooksack Glacier , Seahpo Peak , Nooksack Tower , Icy Peak , Mount Sefrit, and the Picket Range . Melting and receding Ruth Glacier on the northern slope of Ruth Mountain forms the source of the Chilliwack River . Superficial runoffs of precipitation also reach the Nooksack River .
climate
The Ruth Mountain is located in a "Marine West Coast" climate zone of western North America . Most of the weather fronts originate from the Pacific and move northeast towards the Cascade Range . When the fronts reach the North Cascades , they are forced to rise by the high peaks, which sometimes leads to heavy precipitation in the form of rain or snow ( damming effect of the mountains ). This results in high amounts of precipitation on the west side of the cascades, especially in winter in the form of snow. During the winter months, the sky is usually overcast, but due to the high pressure systems over the Pacific, very often cloudless or very little cloudy in summer. Due to the maritime influence, the snow tends to be damp and therefore heavy, so that there is a high risk of avalanches .
geology
The North Cascades are home to some of the most rugged mountains and chains in the entire Cascade Range, as well as pointed peaks and ridges and deep trough valleys . Geological events a long time ago created this diverse topography and drastic height differences that led to the climatic differences. These differences led to a variety of vegetation conditions that are perceived as different ecoregions .
The history of the formation of the cascades goes back to the Eocene many millions of years ago. As the North American Plate pushed over the Pacific Plate , episodes of volcanism continued . In addition, small fragments of the oceanic and continental lithosphere , known as terrans , formed the North Cascades about 50 million years ago .
During the Pleistocene , which began about two million years ago, the repeatedly advancing and receding glaciers dug into the landscape, but also left behind deposits of rock debris. The U-shaped cross-sections of the river valleys are the result of the still ongoing glaciation. Uplifts and faults combined with glaciation were the dominant processes that created the high peaks and deep valleys of the North Cascades.
