Description

Tinkham Peak is situated on the crest of the Cascade Range, on land managed by Mount Baker-Snoqualmie National Forest and Okanogan-Wenatchee National Forest. The east summit, elevation 5,395 feet, is regarded as Tinkham Peak by the USGS, but the west summit, one-quarter mile away, is slightly higher. Tinkham Peak is situated six miles south of Snoqualmie Pass, and neighbors include Silver Peak, one mile to the north-northwest, and Abiel Peak three-quarters mile to the west. Precipitation runoff from the north and east sides of the mountain drains to Keechelus Lake via Cold Creek and Roaring Creek, whereas the south side of the mountain drains to the North Fork Cedar River. Topographic relief is significant as the south aspect rises 2,000 feet (610 meters) above the Cedar in approximately one mile. The Pacific Crest Trail traverses the flanks of the peak and provides access to the Northwest Ridge and Southeast Spur non-technical climbing routes. [4]

Etymology

This geographic landform was named by The Mountaineers and was officially adopted in 1916 by the U.S. Board on Geographic Names to honor Lieutenant Abiel W. Tinkham. [5] He worked as a railroad surveyor when he explored the Snoqualmie Pass area in 1853 and 1854. He is also the namesake of nearby Abiel Peak, and Tinkham Mountain in Glacier National Park, Montana.

Climate

Tinkham Peak is located in the marine west coast climate zone of western North America. [4] Most weather fronts originate in the Pacific Ocean, and travel east toward the Cascade Mountains. As fronts approach, 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 Cascades experiences high precipitation, especially during the winter months in the form of snowfall. Because of maritime influence, snow tends to be wet and heavy, resulting in avalanche danger. [4] 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. [4] The months July through September offer the most favorable weather for viewing or climbing this peak.

<span class="mw-page-title-main">Mailbox Peak</span> Mountain in Washington (state), United States

Mailbox Peak is a 4,841-foot-elevation (1,476 m) mountain located in King County of Washington state. It is set west of the crest of the Cascade Range, on land managed by Mount Baker-Snoqualmie National Forest. Mailbox Peak is situated seven miles east of North Bend, and one mile northeast above the Washington State Fire Training Academy. Precipitation runoff from the south side of the mountain drains into the South Fork Snoqualmie River, whereas the north side drains to the Middle Fork of the Snoqualmie. The summit lies along a ridge containing Dirtybox Peak, its topographical parent, and Dirty Harry's Peak. Topographic relief is significant as the northwest aspect rises nearly 4,100 feet above the Middle Fork in 1.25 mile. The popular Mailbox Peak Trail gains 4,100 feet of elevation over 5.5 miles. Prior to 2014 when the new trail was completed, climbing Mailbox Peak involved 4,000 feet gain in only 2.6 miles along an unmaintained route that was used for conditioning for major climbs, and recruits from the Fire Training Academy would celebrate graduation by carrying a fire hydrant to the summit. The peak is named for a mailbox at the top which functions as the summit register, but this toponym has not been officially adopted by the U.S. Board on Geographic Names.
