4. lies along the western coastline of the United States
This long and very narrow region, is only 40 to 70 miles(65 to 110 km) wide
extends south from the Olympic Peninsula from the Strait of Juan de Fuca
6. Strait of Juan de Fuca
snow-capped Olympic Mountains
evergreen rain-forested Olympic Peninsula
broad sandy ocean beaches, Klamath-Siskiyou
Grays Harbor-Chehalis River lowland
Willapa Bay and Willapa Hills
mouth of the Columbia River
Tillamook Bay Northern Coastal Range
Coos Bay Rogue and Umpqua rivers
Astoria, Oregon Port Angeles, Aberdeen
Six major indentations:
the mouth of the Columbia River

15. Inlets are also sites for the regions largest communities
RIGHT access to world markets through shipping!!!!
Normally most coastal areas are near sea level
Not true in the Pacific Northwest
Elevations approach nearly 8,000 feet
The regions profile is bell-shaped.
The profile begins at sea level, climbs to the top of the Olympic Mountains and the Coastal Range, then rapidly descends to nearly sea level again.
Because of off shore warm currents British Columbia, and southern Alaskan (coast-lines), have a very mild, but moist climate throughout the year.
This climate provides lush vegetation and supports dense coniferous (softwood) forests.
Extensive ever-green forests cover the Coastal Region except were development has taken place.
The Coastal Regions climate is the most moderate in the Pacific Northwest
Winter 35F and 55F
Summer 55F to 75F
With lots of rain fall
Coastal Region greatly exceeds the norm in the Pacific Northwest and the western United States.
40 inches (101 cm) a year
200 inches (508 cm) of rainfall annually in the Olympic Mountains
27. Economic Activities
One result of the regions mild rainy cli-mate is the abundance and variety of plant and animal life.
main economic activities include fishing, forestry, general farming, and tour-ism.
28. located between the mountains and hills of the Coastal Region and the Cascade Range.
extends about 400 miles (640 km) north to south but is only 50 to 70 miles (80 to 110 km) wide
The region is the most heavily populated, urbanized, and industrialized in the Pacific Northwest.
30. The Western Lowlands are made up of
three large subregions:
1) the Puget Sound Trough
2) the Chehalis-Cowlitz-Columbia river valleys
3) the Willamette River Valley
31. The Western Lowlands are made up of The Puget Sound area has hundreds of small and medium sized islands,
Such as: San Juan Islands, Whidbey Island, Vashon Island, and Bainbridge Island
It is also has many peninsulas Olympic Peninsula, Kitsap Peninsula.
32. Puget Sound Trough
located in western Washington
It is a densely populated fertile lowland that is a hub of economic activity.
Major urban areas such as Seattle,Tacoma, Bellevue, Bremerton, Bellingham, Everett, and Olympia
All are centers of urban and industrial activities.
34. Due to glacial erosion, Puget Sound has an irregular shoreline and numerous deep, sheltered harbors such as:
Hood Canal-Bangor, Elliott Bay-Seattle, Commencement Bay-Tacoma, Everett, Bremerton, Olympia, Anacortes, and Bellingham.
43. Chehalis-Cowlitz River Valleys
The second subregion within the West-ern Lowlands contains three major river valleys:
1) Chehalis River
2) Cowlitz River
the Columbia River Gorge
Why are these regions not as populated?
44. Willamette Valley
the third subregion
The Willamette River Valley was the historic objective of thousands of early pioneers.
The Willamette River produced a broad fertile valley that is a prime agricultural region.
46. Willamette Valley
cities as Portland, Eugene,Salem, Springfield, Beaverton, Corvallis, Al-bany, Lake Oswego, Gresham.
50. Physical Terrain
elevation ranges from sea level to about 1,000 feet (305 m).
This region is physically unique because of its many river valleys and flood plains. Thus, the total precipitation is generally less.
Marine West Coast
The region receives slightly less precipitation than the Coastal Region.
The Western Lowlands lie in the rainshadow of the Coastal Range and Olympic Mountains.
precipitation is generally less than on the windward slopes
average annual rainfall ranges from 15 inches (38 cm) at Sequim,and Eugene.
100 inches (254 cm) in the western foothills of the Cascade Mountains
The regions average is about 40 inches (100 cm) annually.
Winter temperatures range from 35F to 55F
summer temperatures generally range between 65F and 85F
The Western Lowlands economy is be-coming more industrialized.
55. Economic Activities
vegetables, berries, flower bulbs, fruits, nuts, nursery plants and shrubs, some grains, dairy products, and beef.
Western Lowlands economy is be-coming more industrialized.
Western Lowlands economy is be-coming more industrialized transportation equipment, electronics, and high technology
58. Just east of the Western Lowlands, also lying along a north-south axis, are the Cascade Mountains.
They extend from southern British Columbia, Canada, through the states of Washington and Oregon and end in northern California.
61. Natural Barrier
a formidable physical, climatic, and transportation barrier.
averaging about 6,000 feet (1,800 m) in elevation with many volcanic peaks above 10,000 feet (3,000 m)
Cascade Range has only a few low mountain passes and only one major lowland, where the Columbia River cuts through the Columbia Gorge.
The Cascade Mountains are part of the Pacific Oceans Ring of Fire.
Tallest Mount Rainier 14,411
Smallest Mt. St. Helens 8,365 ft
these north-south mountains are a physical barrier to the regions climate
West wet East dry
100 inches (250 cm) on the western slope and decreases to only 20 inches (50 cm) on the eastern slopes
69. Rainier set the world record with 1,224.5 inches (3,110.2 cm) or 102 feet of snow between February19, 1971, and February 18, 1972.
heavy annual snowfall provides the late spring and early summer river runoff, especially significant for those eastern slope rivers flowing through the semiarid regions of Washington and Oregon.
70. Highland Climate
Due to great range in elevation have climates that are more moist and very mild. summer maximum temperatures are cooler, but the winter minimum temperatures are colder.
72. Difference in vegetation east vs. west
West dense evergreen coniferous forests Fir species
Animals birds, small animals, and big game animals, such as elk, black bear, cougar or mountain lion, mule deer,bighorn sheep, and mountain goats.
The Cascade Mountain Region is sparsely populated.
Mountains is owned or controlled by either the state or federal government.
76. The largest geographic region of the Pacific Northwest.
The region covers about 193,000 square miles
It is the worlds second largest lava plateau.
400 miles (640 km) from north to south and 500 miles (800 km) east to west
77. lies between the Cascade Mountains to the west, the Rocky Mountains to the east and north, and the Great Intermountain
The Columbia Plateau was constructed by as many as 55 different lava flows.
79. Sub regions
northern part Columbia Basin
the sub regions include:
the Waterville Plateau
the Quincy Basin
the Channeled Scablands
the Palouse Hills
the Kittitas Valley
the Yakima Valley
the Pasco Basin
81. The central parts of the Columbia Plateau are interrupted by the Seven Devils, Wallowa, and Blue mountain ranges.
On the Oregon side of the Columbia River is the Umatilla-Deschutes Plateau.
87. The southern and southeastern sections are dominated by the Harney High Lava Plains and the Upper Snake River Valley respectively.
arid to semiarid region characterized by hot, sunny summers and cold winters.
region is virtually surrounded by the Cascade and Rocky mountains. These mountain barriers have a drastic effect upon annual precipitation amounts received by the region
annual precipitation below 20 inches
Summer 100F Winter below zero
90. Natural Vegetation
sparse grassland and sagebrush-bunch grass
Wildlife we know
human inhabitants are un-evenly distributed over this huge area.
91. Economic Activities
mixture of farming and manufacturing
a long growing season, and abundant irrigation water allow farmers to produce outstanding yields of wheat, bar-ley, oats, hops, alfalfa, corn, beans, apricots, potatoes, sugar beets, apples, pears, peaches, grapes, cherries, vegetables, and specialty crops. In addition, the dry grasslands are excellent grazing areas for cattle, sheep, horses, and other livestock.
92. Forms the northernmost subregion in eastern Washington.
It extends east of the Cascades across the northeastern portion of the state.
The Columbia and Spokane rivers form its southern boundary
94. Physical Features
very rugged and mountainous.
It includes the Okanogan Highlands, San Poil and Selkirk mountains, and a small portion of the Rockies.
Includes several peaks over 8,500 feet
95. Physical Features
The Columbia River divides this subregion into two parts.
The western portion includes the Methow, Okanogan, and San Poil rivers.
The eastern portion includes the Pend Oreille,Colville, and Spokane rivers..
Cold winters and warm summers.
Summers are warm with little precipitation
The higher elevations have a highland climate, and lower elevations are semiarid.
