Riddle Peaks, also known as Riddle Peak, is an 8,212-foot (2,503-metre) mountain summit located at the head of Riddle Creek in the
Topographic relief is significant since the southern aspect of the mountain rises 5,000 feet above the Railroad Creek valley in approximately 2 mi (3.2 km). The first ascent of the peak was made September 11, 1940, by Everett and Ida Zacher Darr, Joe Leuthold, and Eldon Metzger via an easy ridge from Tenmile Pass.[4]
Climate
Lying east of the
Cascade Mountains. As fronts approach the North Cascades, they are forced upward by the peaks of the Cascade Range, causing them to drop their moisture in the form of rain or snowfall onto the Cascades (Orographic lift). As a result, the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall.[4]
With its impressive height, Riddle Peak can have snow on it in late-spring and early-fall, and can be very cold in the winter.
Geology
The North Cascades features some of the most rugged topography in the
glacial valleys. Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to the various climate differences. These climate differences lead to vegetation variety defining the ecoregions
in this area.
The history of the formation of the Cascade Mountains dates back millions of years ago to the late
During the Pleistocene period dating back over two million years ago, glaciation advancing and retreating repeatedly scoured the landscape leaving deposits of rock debris.[5] The U-shaped cross section of the river valleys is a result of recent glaciation. Uplift and faulting in combination with glaciation have been the dominant processes which have created the tall peaks and deep valleys of the North Cascades area.
