Not Man Apart. [2] The average high temperature in January is 36.3 °F (2.4 °C), and the average high in July is 61.9 °F (16.6 °C) with temperatures also varying by elevation. Physiographically, they are a section of the larger Pacific Border province, which in turn are part of the larger Pacific Mountain System physiographic division. The Coast Range creates a rain shadow effect by forcing moisture laden clouds to rise by expelling moisture. Hood Ski Bowl: 3500: Timberline … [1] By the Early Oligocene period c. 30 million years ago the current coastline was in place and erosion has continued to shape the range. The range creates a rain shadow effect for the Willamette Valley that lies to the east of the mountains, creating a more stable climate and significantly less rain than the coastal region of the state. Elevation. The Oregon Coast Range is an ancient volcanic island chain that collided with North America 50 million years ago. 1. [12] Bear are black bear while deer are mule and black-tailed deer species. This approximately 90-mile (140 km)[10] long mountain range contains mountains as high as 4,097 feet (1,248 m) for Marys Peak. Fish, including salmon and trout, and other aquatic life inhabit the streams and rivers flowing through the range. (Well, it is not that nice and neat. [3] This shields the Willamette Valley and causes a less maritime climate with hotter summers and less precipitation than the Oregon Coast. [1] Also, the Oregon Coast Range is home to over 50 mammal species, over 100 species of birds, and nearly 30 reptile or amphibian species that spent significant portions of their life cycle in the mountains.

[1] These Roseburg volcanics were followed by the Siletz River Volcanics in the northern portions of the range, and lastly a series of basalt flows from the Columbia River basalts also added to these formations with some smaller flows in-between. [6] Forests here are considered to be some of the most productive timber land in the world. [5], The southernmost section of the Coast Range is located in the southwest portion of Oregon between the middle fork of the Coquille River in the south and the Umpqua River on the north. The oldest portions of the range are over 60 million years old, with volcanics and a forearc basin as the primary mountain building processes responsible for the range. A mild maritime climate prevails throughout the range with temperature and precipitation varying due to elevation and distance from the coastline. The Pacific Crest Trail traverses left and right across the pass; Mount Hood's northwest face is visible in the background. Larger animals that live in these section include deer, elk, bobcat, and bear. 10, No. Both the state and federal government manage forests in the Oregon Coast Range. 1.

This page shows the elevation/altitude information of Oregon, USA, including elevation map, topographic map, narometric pressure, longitude and latitude. The two maps shown here are digital base and elevation maps of Oregon. This north-south running range extends over 200 miles (320 km) from the Columbia River in the north on the border of Oregon and Washington, south to the middle fork of the Coquille River. Orr, Elizabeth and William Orr, and Ewart Baldwin. [2] Species include peregrine falcons, pileated woodpeckers, olive-sided flycatcher, and western bluebirds among others. Cascade Range. [1], Additional basalt flows originated from Eastern Oregon and added to the layers that were uplifted, as the newer Cascade Mountains had not yet been formed. Higher resolution maps like these and many other digital maps, wall maps, custom radius maps, travel maps, travel guides, map software, and globes and games, for business and the classroom, are available to purchase from - The World's Largest Maps Store!. [2] Annual precipitation differs from 60 inches (1,500 mm) in some parts to up to 120 inches (3,000 mm), with the higher amounts coming in the higher elevations. There are several words in use for a mountain pass in Oregon; the usage for each is: Battle Mountain Summit (Umatilla County, Oregon), Beech Creek Summit (Grant County, Oregon), Bingen Gap (Klickitat County, Washington), Black Tank Saddle (Lincoln County, Oregon), Bly Mountain Pass (Klamath County, Oregon), Brogan Hill Summit (Malheur County, Oregon), Butch Foster Saddle (Grant County, Oregon), Canyon Creek Pass (Douglas County, Oregon), Captain Keeney Pass (Malheur County, Oregon), Cline Hill Summit (Lincoln County, Oregon), Cornelius Pass (Multnomah County, Oregon), Crotchline Saddle (Lincoln County, Oregon), Cummings Hill Summit (Wheeler County, Oregon), Desolation Saddle (Lincoln County, Oregon), Fingerboard Saddle (Wallowa County, Oregon), Free and Easy Pass (Josephine County, Oregon), Freeland Saddle (Josephine County, Oregon), Freezeout Saddle (Wallowa County, Oregon), French Gulch Divide (Jackson County, Oregon), Government Harvey Pass (Lake County, Oregon), Green Springs Summit (Jackson County, Oregon), Grouse Creek Gap (Jackson County, Oregon), Gumjuwac Saddle (Hood River County, Oregon), H. B. [7] Trees include primarily Sitka spruce, western redcedar, Douglas-fir, and western hemlock. 7. Kerr, Andy.

New content will be added above the current area of focus upon selection [11] Portions of the range are inside the Siuslaw National Forest along with three designated wilderness areas: Drift Creek Wilderness, Cummins Creek Wilderness and the Rock Creek Wilderness.
