It is located within North Cascades National Park. It rises steeply from Diablo Lake, one of the reservoirs on the Skagit River. It is part of a group of peaks that form the northern end of a chain running south through climbing destinations such as Colonial Peak, Paul Bunyans Stump, and Snowfield Peak. Like many North Cascade peaks, Pyramid Peak is more notable for its large, steep rise above local terrain than for its absolute elevation. Precipitation runoff from the mountain drains into Diablo Lake and Skagit River. Pyramid Peak was first climbed in 1931 by William Degenhardt and Herbert Strandberg of the Seattle Mountaineers.[4] The approach is via the Pyramid Lake Trail, starting near Diablo Dam on the North Cascades Highway. From the lake, it's route-finding up Pyramid Arm and to Colonial Glacier. ClimatePyramid Peak is located in the marine west coast climate zone of western North America.[5] Most weather fronts originate in the Pacific Ocean, and travel northeast toward 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 west side of the North Cascades experiences high precipitation, especially during the winter months in the form of snowfall.[6] During winter months, weather is usually cloudy, but, due to high pressure systems over the Pacific Ocean that intensify during summer months, there is often little or no cloud cover during the summer.[7] Because of maritime influence, snow tends to be wet and heavy, resulting in high avalanche danger.[7] References1. ^{{cite peakbagger|1837|Pyramid Peak, Washington}} {{stack|{{portal|Washington}}}}2. ^{{cite peakbagger|1837|Pyramid Peak, Washington}} 3. ^{{cite peakbagger|1837|Pyramid Peak, Washington}} 4. ^1 {{cite book |last=Beckey |first=Fred W. |title=Cascade alpine guide, Volume 2: Stevens Pass to Rainy Pass |edition=2nd |year=1996 |isbn=978-0-89886-838-8}} 5. ^{{cite book |last=Beckey |first=Fred W. |title=Cascade alpine guide, Volume 2: Stevens Pass to Rainy Pass |edition=2nd |year=1996 |isbn=978-0-89886-838-8}} 6. ^{{cite book |last=Beckey |first=Fred W. |title=Cascade alpine guide, Volume 2: Stevens Pass to Rainy Pass |edition=2nd |year=1996 |isbn=978-0-89886-838-8}} 7. ^1 Beckey, p. 16 External links
