Massive old growth Douglas Fir stump with springboard cut, now a forest nurse
This stump, probably logged a 100 years ago, dates back untold 100s of years. This area was once selectively logged which left a number of old growth trees and stumps to shelter and nourish the ancient forest floor of the Stimpson Family Nature Preserve.
This diary may seem a bit disjointed but each part is in fact related and I hope of interest to this group. Each of the components emanates from a beautiful beach and pertains to various environmental and geologic issues currently and historically in play in Whatcom County and Washington State.
Point Whitehorn Marine Reserve Beach
Some items can be seen as hopeful, positive, and far sighted like the State’s aquatic reserve program. Others are worrisome and seen by many as looming disasters waiting to happen such as the potential coal export terminal slated to be situated in this area. And finally, I describe some geology of how our beautiful region, including this beach became what it is today.
The Columbia River flowing through carved out basalt cliffs at Vantage Washington
This diary describes an Ice Age Floods Institute field trip that I took in September last year that explored some of the remnants of the ice age floods in the pacific Northwest that periodically burst from Glacial Lake Missoula and later from Lake Columbia over the last approximately one million years. This particular field trip covered the Central Columbia region, the Hanford Reach National Monument, White Bluffs, including the larger Pasco Basin. This diary covers just one segment of this huge flood area that is too large to describe in a single diary. I described the part that flooded the Walla Walla Valley previously and plan to cover other areas in the future.
Some of the largest cataclysmic geologic events on earth occurred in what is now the Pacific North West. About 11 million years of volcanic flow activity, ending about 6 million years ago, created the Columbia Plateau with basaltic lava formations up to two miles deep. This huge basaltic plateau covering much of Eastern Washington and Oregon and adjacent parts of Idaho was later inundated by massive Ice Age floods ending about 15,000 calendar years ago. The scale of these events has been seldom seen elsewhere as it carved a landscape that appears other worldly. (In fact, the resulting terrain so closely matches that seen on Mars that NASA tested the Sojourner robotic rover here before its 1997 mission to Mars. (Bjornstad, 2006).
Scablands from basalt and flooding
The Columbia River continues to cut into basalt
As many as 100 floods deposited layers of sediment atop the basalt that today provide the soil for growing some of the best wine grapes and hence wines in the country and in some cases, the world. These are the wines of Oregon and Washington State.
Spring time is Rhododendron time around the world. These prolific bloomers are native to Asia, North America, Australia, and Europe. They are members of the Genus Rhododendron and the Family of Ericaceae (Heaths). The name is derived from ancient Greek (rhódon “rose” or “red“) and déndron “tree”). There are some 800 to 1,000 species and 28,000 cultivars listed by the Royal Horticultural Society. Azaleas are a subgenera of Rhododendron.
