Editing Olympic National Park (section)

===Glaciated mountains===
Within the center of Olympic National Park rise the [[Olympic Mountains]] whose sides and ridgelines are topped with massive, ancient [[glacier]]s. The mountains themselves are products of [[accretionary wedge]] uplifting related to the Juan De Fuca Plate [[subduction zone]]. The geologic composition is a curious [[mélange]] of basaltic and oceanic sedimentary rock.{{cn|date=November 2024}} The number of glaciers within the national park declined from 266 in 1982 to 184 by 2009 due to the effects of [[climate change]].<ref>{{cite web |title=Glaciers and Climate Change |url=https://www.nps.gov/olym/learn/nature/glaciers.htm |publisher=National Park Service |accessdate=November 27, 2024}}</ref><ref>{{cite news |last=O'Sullivan |first=Joseph |date=August 25, 2021 |title=The majestic Hoh Rain Forest is one of the natural wonders of Washington state; venture in and wander |url=https://www.seattletimes.com/life/outdoors/the-majestic-hoh-rainforest-is-one-of-the-natural-wonders-of-washington-state-venture-in-and-wander/ |work=The Seattle Times |accessdate=November 27, 2024}}</ref>

The western half of the range is dominated by the peak of [[Mount Olympus (Washington)|Mount Olympus]], which rises to {{convert|7965|ft}}. Mount Olympus receives a large amount of [[snow]] and consequently has the greatest glaciation of any non-volcanic peak in the contiguous United States outside of the North Cascades. It has several glaciers, the largest of which is [[Hoh Glacier]] at 3.06 miles (4.93&nbsp;km) in length. In the east, the range becomes much drier due to the rain shadow of the western mountains; the eastern mountains include numerous high peaks and craggy ridges. The tallest summit in the eastern Olympics is [[Mount Deception (Washington)|Mount Deception]], at {{convert|7788|ft}}.
