Connecting with friends: Pacific Northwest, June 2022
Our Route
We plotted an unhurried course using byways and National Forest roads whenever feasible. Red stars in the maps below indicated places where we stayed. Accommodation included designated campgrounds, dispersed sites and the luxury of friends’ homes in the Methow Valley, WA and Portland, OR.
Castle Crags
Castle Crags monolith and its surroundings provide a great introduction to the Klamath Mountains geomorphic province, which consists of multiple fragments of oceanic crust that have been added to the western edge of the North American continent by plate-tectonic processes. Rocks immediately surrounding Castle Crags consist mostly of Ordovician-aged (443–490 million year old) oceanic crust referred to as the Trinity ultramafic sheet. (See July 2021 blog for more on ultramafic rocks.) The spires and domes of Castle Crags are the result of an intrusion of granitic magma around 160 million years ago. Over time, the granitic pluton was exposed and shaped by erosion.

Right: Castle Crags Ivesia (Ivesia longibracteata) is a flowering plant in the rose family and is known only from Castle Crags.
Left: Sugarstick (Allotropa virgata) is among a unique group of species, referred to as the Monotropoideae, that do not have chlorophyll and are incapable of photosynthesis. These plants depend on root-associated fungi (mycorrhizae) to transport nutrients and carbohydrate to them from the roots of host trees such as conifers.
Right: Trail to Indian Springs.
The Cascade Range
The Cascades extend for over 700 miles from Mount Lassen in California, through Oregon and Washington, to southern British Columbia. The range captures moisture-laden westerly winds which results in heavy precipitation along its western slopes. Precipitation diminishes on the eastern slopes as the distance from the summit increases and the elevation decreases. On our journey north we travelled on the drier side of the Cascades and returned south via a more westerly, wetter route.

Columbia River surprise
It rained solidly all day, so we pushed on to The Dalles by the Columbia River and enjoyed a Mexican meal. Driving to camp after dinner, we heard a prolonged squeal from under the hood. Oil everywhere - a seal in the vehicle’s power steering had failed. Next morning the van was towed to Precision Automotive who kindly adjusted their schedule to accomodate our repair. We checked in at a local hotel, visited an art center and sampled local brews at Clock Tower Ales while watching Steph Curry’s crew secure match #5 of the NBA finals.
Left: Hey, better than pushing the van into town. Right: The Dalles Art Center - a pretty sight.
Methow Valley
The upper end of Eastern Washington’s Methow Valley harbors four settlements - Twisp, Winthrop, Mazama and Carlton (listed in descending size). The area offers excellent winter and summer outdoor sport opportunities and is increasingly popular with internet-linked workers who have been liberated from office attendance by the pandemic.
Here we united with fine friends, some of whom had driven from Seattle for the occasion. Suffice to say it was wonderful to see everyone! Great company, good humor, excellent food, enjoyable activities and gracious hosts. A splendid gathering!
Locals remarked how green the countryside looked for this time of year. We heard the same in Oregon. Rivers were running high, warblers were singing and bears were out and about. Below is a sampling of Methow images.

Bottom row, Left & Right: Female/immature Cassin’s Finch
Top 4 rows: Male & immature/female Cassin’s Finch. This species is seen year round in coniferous forests of the mountainous West.
Bottom row, Left: Male Cassin’s Finch. Right: Male breeding American Goldfinch.
John Cassin (1813-1869) was a Philadelphia-based ornithologist who has five American birds named after him and four more from elsewhere in the world.

Left & Right: Juvenile/female Red Crossbill.
Crossbills are seed-eaters and the only birds in the world with truly crossed bills, a characteristic that allows them to bite and pry between the scales of conifer cones. At least 9 forms of Red Crossbills occur in US. They have differences in bill size and structure. In general, the larger & stouter-billed types forage most efficiently on larger and harder cones (pines); the smaller-billed types forage most efficiently on smaller and softer cones (spruces, firs, hemlocks).

Cascade backroads in Washington
After ten delightful days in the Methow Valley, we turned south, heading to friends in Portland, OR. Traveling within the Cascades, we explored several areas immediately east of Rainier, St. Helens and Hood mountains. The region receives substantial precipitation; the snow-line was closer and the vegetation lusher than that seen during our drive north to Methow. Some of the unpaved, single lane logging roads required careful driving - perfect speed for roadside botanizing and birding! Took the time to enjoy day-hikes in Wenatchee, Gifford Pinchot & Hood National Forests, Goat Rocks Wilderness and Mount St. Helens National Monument.

Oregon: fireworks - ancient & modern
We spent Independence weekend with good friends who were also work colleagues. Again, wonderful to reconnect in person! We were treated royally! Visited Portland’s exquisite Japanese Gardens, shopped at the Sunday produce market and strolled beside the Willamette river.

Volcanism in the Pacific Northwest
Similar to Washington, Oregon has ample evidence of past fiery explosions.
Cascade volcanoes
The Cascades constitute part of the American Cordillera, an almost continuous sequence of mountain ranges that form the western "backbone" of North, Central and South America. The Cordillera is also the eastern half of the Pacific Ring of Fire.
Cascade Range volcanoes receive a relatively continuous supply of magma derived from the subduction of the Juan de Fuca Plate under the North American Plate. Moderately viscous lavas, such as andesite, tend to form the steeper stratovolcanoes such as Mt. Hood, Oregon’s highest mountain (11,239 feet). Most of the present volcano formed since about 500,000 years ago but beneath those lavas lie the remains of the Sandy Glacier Volcano, which dates back about 1.5 million years. Mt Hood’s recent eruptions include two major events, one about 1,500 years ago and one between 1781-1795, as well as two minor ones in 1859 and 1865.
Explosive eruptions tend to occur when the erupting magma is rich in water or carbon dioxide. The decrease in pressure experienced by magmas as they rise through the crust allows these compounds to become highly energized gases. If the magma is also highly viscous because a high silica content, the volcanic conduits can become plugged and the subsequent eruptions are extraordinarily violent, such as the 1980 eruption of Mt. St. Helens.

Volcano hazards
Tephra (rock fragments) and ash
Lava flows. Lava usually advances slowly but molten basalt that is confined within a channel on a steep slope can flow at 20 mph.
Lahars occur when hot gas, rocks, lava and debris mix with rainwater and melted ice and form a violent mudflow that can pour at 120 mph down a volcano’s slopes.
Volcanic gas - water vapor, carbon dioxide, sulphur dioxide, hydrogen sulphide & toxic hydrogen halides (HF, HCl, HBr)
Pyroclastic flows are avalanches formed by hot gas, ash, lava & other volcanic matter. They typically travel at 50 mph or faster.
Volcanic landslides. A St. Helens landslide (5/18/1980) reached speeds of 100-180 mph and surged over a 1,300 ft. ridge located 3 miles from the volcano.
Crater Lake caldera with Wizard Island
Crater Lake
Crater Lake formed through the explosive eruption (about 50 times greater than Mt. St. Helens) and collapse of Mt. Mazama about 7,700 years ago. Crater Lake lavas are related to dacite and rhyolite which are very viscous. The eruption was so large that it emptied its magma chamber and the mountain collapsed into the void to form a deep caldera. Overtime, it was filled with rainwater and snow melt.
Wizard Island is the top of an andesitic volcano that erupted within a few hundred years after the caldera formed. Phantom ship is an outcrop of 400,000 year old andesite and is the oldest exposed rock in the caldera.

Volcanoes can affect climate
The most significant climate impacts from volcanic injections into the stratosphere come from the conversion of sulphur dioxide to fine sulphate aerosols. These increase the reflection of radiation from the sun back into space, cooling the earth’s lower atmosphere. Mount Pinatubo’s eruption on 6/15/1991 cooled the earth’s surface for 3 years, by as much as 1.3 degrees F.
Present day global volcanic carbon dioxide emissions constitute less than 1% of the carbon dioxide released currently by human activities.
Home again - feeders to fill
Sugar (by John Kooistra)
Hummingbirds too fast to count
hustle flowers
and flit through my air space
where I flinch again
and laugh.
Everyone gets something
from this performance.
Entertainment for me,
sustenance for the hummers,
and pollination for the blossoms
dressed in red
like single women at the bar.
