Columbia Basin: Climate and latitude
Arid continental (average diurnal shift 28º, may be up to 40º). 6-12 inches of rain annually; irrigation required for vinegrowing.
46º N, or more
What are synclines and anticlines?
How were these created?
Anticlines are ridgelines
Synclines are the valleys between them
In Washtingon, created by tectonic compression during the Miocene Epoch.
Why is rainfall so scarce in eastern Washington?
As it hits the Cascade Range, Pacific air is pushed upward, cooled and condensed into clouds which release their moisture as precipitation.
This creates a rain shadow effect for the Columbia River Basin in eastern Washington
-the western slopes of the Cascades receive over 80 inches of rainfall annually, yet 50 miles to the east the climate is desert-like.
What do the Cascades do for Eastern Washington.
-rain shadow effect
-responsible for the Columbia Basin’s continental climate -they block the moderating maritime air from moving further inland
What do the Rockies do for the Columbia Basin?
they are located to the north and east so they shelter the region from icy polar air masses.
What is the Yakima Fold Belt, and how does it affect viticulture?
The low-lying topography of south-central Washington, striated by east-west ridges, from 4,000ft high at most, and generally no more than 1,000ft high in the valleys.
The anticlines restrict airflow and cause a temperature inversion layer, as cool air bottlnecks in the synclines. This means that valley vineyards are colder, have a wider diurnal shift and more frost pressure than higher elevation vineyards.
How are Washington’s ripest vineyards situated?
On anticlinal ridges, facing south (seen in Red Mountain, Wahluke Slope, Horse Heaven Hills, and elsewhere); elevation and aspect grants higher degree days, temperatures, and lesser risk of frost.
What are two techniques used to protect against the winter cold?
Dual trunk training and buried canes.
Dual trunk is just what it sounds like, starting an inch or so above the soil; statistically, if one trunk dies in the winter, the other may survive.
Buried cane is used with low cordon trained vines; one fruiting cane is buried by heaping up soil around it so as to protect it from the cold; if the aboveground canopy dies over the winter, the buried cane can be unearthed and used in the coming year.
When were the Missoula Floods, and what caused them?
12,000-18,000 years ago, 2 to 3 times per century as the glacier lake periodically broke through the retreating Cordilleran Ice Sheet.
The Wallula Gap bottlenecked the onrushing water, causing massive flooding of the Columbia Basin.
What are Touchet beds?
Nutrient rich deposits of gravel and other flood sediments, up to 100ft deep at the lowest points of the Columbia, Yakima, and Walla Walla Valleys.
At what elevation did the Missoula floods top out?
1200ft.
What does the term Eolian mean?
Shaped by wind - referring to the loess soils of the Columbia and Willamette valleys.
Who is the father of Washington wine, and why?
Dr. Walter Clore
Pioneered the study of properly siting vinifera in Washington (prior to that, grapevines were either native, or killed off every few years by the cold); mentored the nascent WA wine industry from the 1940’s to the 1970’s.
Who owns the majority of Snipes Mountain? What are the two vineyards planted there?
Upland Estate
Upland Vineyard and Harrison Hill
