Abiel Peak is a 5,365 ft (1,640 m) mountainsummit located in easternKing County ofWashington state.[4] It is set 1,000 feet west of the crest of theCascade Range, on land managed byMount Baker-Snoqualmie National Forest. Abiel Peak is situated six miles south-southwest ofSnoqualmie Pass, and neighbors includeSilver Peak, three-quarters mile to the north-northeast,Tinkham Peak three-quarters mile to the east, andHumpback Mountain two miles to the northwest. Precipitationrunoff from the south side of the mountain drains into headwaters of Tinkham Creek which is a tributary of the North ForkCedar River, whereas the north side of the mountain drains into Annette Lake, thence the South ForkSnoqualmie River via Humpback Creek.Topographic relief is significant as the north aspect rises 1,860 feet (570 meters) above Annette Lake in one-half mile.
This geographic landform was named byThe Mountaineers and has been officially adopted by theU.S. Board on Geographic Names to honor Lieutenant Abiel W. Tinkham.[5][6] He worked as a railroad surveyor when he explored the Snoqualmie Pass area in 1853 and 1854. He is also the namesake of nearby Tinkham Peak, andTinkham Mountain in Glacier National Park, Montana.
Abiel Peak is located in themarine west coast climate zone of westernNorth America.[1] Mostweather fronts originate in thePacific Ocean, and travel northeast toward theCascade Mountains. As fronts approach, they are forced upward by the peaks of the Cascade Range, causing them to drop their moisture in the form ofrain orsnowfall 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 ofmaritime influence, snow tends to be wet and heavy, resulting in highavalanche danger.[1] 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.[1] The months July through September offer the most favorable weather for viewing or climbing this peak.
