Geology Digression (skippable) - I’ve been asked about this numerous times; last week’s earthquake swarm in the
Ridgecrest area of SoCal was dramatic, but not particularly surprising in its
geography.
The San Andreas Fault system
defines the boundary between the North American Plate and the Pacific Plate. The Pacific Plate is moving northwest
relative to North America, but they are jammed together, and the intermittent jerky
motions as they slide past each other are what we experience as
earthquakes. Anyway, depending on the
interpretation, on 75%-90% of the relative plate motion occurs along the
SAF. The rest takes place along the
Eastern California Shear Zone, basically an oblong blob running from west of
Death Valley NNW up the east side of the Sierra Nevada (through the Owens
Valley), dying out (at present) at about the latitude of Reno.
Why?
If you look at the map below, the SAF is the thick orange line (the red lines are other major faults). Notice that it
bends north of LA: this is not a happy plate boundary.
What’s probably happening (and has happened in the past, several times)
is that the boundary is gradually jumping inboard to east of the Sierra Nevada. So in five million years or whatever LA won’t
be off San Francisco: most of the motion will be further east. Maybe.
Check back with me then.
The
tight cluster of balloons on this map shows all the seismicity associated with
the Ridgecrest event as of Sunday. They occurred
on several of the major lateral faults that transfer motion from the SAF to the
ECSZ.
Bottom
line: if you live in the Bay Area, worry about this instead.
Yes,
this the level of information I used to torture my UCB students.
Thursday July 27 – Thursday July 4 – A pause
in Walnut Creek. I arrived the previous
evening after a long night flight, only to have it be night again. I tend to have really bad jet lag after long
eastward flights, and this return was not anomalous. So during this travel parenthesis, I:
- Unpack, do laundry, wear different clothes.
- Hire a plumber to replace my leaking hot water heater.
- Trim the pomegranate tree, and do enough other yard work to make my house looked lived in.
- Sleep when I can, within reason, drifting when possible towards Pacific Time.
- Yoga. Taiji. Meditate. Gym.
- Write. Triage DSLR photography.
- Catch up with friends and family.
- Five books, three movies, four whole issues of The New Yorker
- Go walkabout or runabout, often before dawn.
- Run a 4th of July 5k race, and do my first sub-eight minute mile since knee issues:
Friday July 5 – Button up
the house, and off again, to OAK this time.
A delay, almost expected for an end of day Southwest flight during the
summer weather season. My app says that
my flight to Portland is this 737’s eighth segment of the day.
So,
I do my usual several laps of the terminals; about a quarter mile:
Warmed
up, I watch the tide rise:
Observing
and trying not to judge how different this domestic traveler crowd is from what
I saw in Sydney, Auckland, Brisbane, Perth, Singapore, Seoul, and SFO. More people dressed in fashion-inspired
clothes that don’t fit well. Or in
pajamas. I want to say there are lots
more high-BMI Americans waddling around, but I don’t trust my biases or travel
impatience. It could just be my ongoing
perceptual adjustment; I unconsciously expect to be around a lot of Koreans
rather than the broader spectrum of Americans. I will not miss dreaming in Korean, i.e.,
people saying things I can’t understand.
A
plane, the usual super-efficient Southwest transition (allowing for
pre-boarding of seven wheelchairs and three “companion” animals):
North,
late afternoon over the Coast Ranges and Central Valley. Hazy, but not much fire smoke. Yet.
Eventually over the Cascade volcanoes.
A nice well-behaved chain at a convergent plate boundary, compared to
the complexity of the Taupo Volcanic Zone.
Crater Lake from 32k feet:
PDX. Portland seems minuscule after Seoul and
Singapore. Budget gives me a Nissan
compact, which while brand new, seems to have had its engine transplanted from
dear MG back in Auckland. I fear
accelerating, as I head southwards on I-5.
First
destination is Salem, and an overnight visit with my friends Daisy and
Bruce. We catch up some before jetlag
flatlines. I taste a chocolate
peppermint stout. It is not awful.
Saturday July 6 - A morning walk with Daisy, Bruce, and Ollie,
their Jack Russell terrier:
Not
posed, thanks to Daisy for the picture.
No
dust, no flies. There are flowers:
Away,
further south on Eugene. I’m impressed
all over again at how wide the Willamette Valley gets. This compressional plate boundary, defined by
the Cascadia Fault Zone off the coast (as due as the San Andreas for a major
event), is mashed up the edge of the continent, forming the high terrain all
the way from the CA/OR coastal ranges to the Olympics; the Willamette Valley
and the trough up through Puget Sound are an area of downwarping behind
this. The Willamette was further carved
by the numerous Pleistocene glacial floods.
The Valley narrows as I go south; more faulted blocks of volcanic rock
poking up through the alluvium.
I
guess I haven’t explained this segment of my trip. I am going to the “Even Decade Party”, a
reunion of the West Coast part of my family:
Seven
birthdays with ages ending in zero, ranging from my father at 90 to cousins at
10. Clever. I didn’t think of it. Anyway, spending time with family – arguably
the wing I see the most and am closest too – seemed the right way to conclude
the sabbatical travel phase.
So
up the McKenzie River drainage, Springfield, Walterville, and to Leaburg. My cousin Charis rented a house, which I will
share with her, her boys, and boyfriend.
I am happy to sleep on the deck, with a view of the Goodpasture Covered
Bridge (one lane, wooden):
I
am not sure where the pasture is, presumably further up into the national
forest.
It’s
sort of a weird house, in terms of layout.
It’s three stories but narrow, built into the cut bank of the river to
maximize the views:
Lots
of stairs. Lots of decks. It functions well for family gatherings.
We’re
on a narrow reservoir behind a small hydroelectric dam in Leaburg. The water is cold, and full of anglers:
I
enjoy the view and the forest before the remainder of the immediate family
arrives:
We
have a barbecue and reacquaint:
I
subject interested parties to descriptions of my trip, with maps. They don’t hate me.
Sleep,
eventually. Today would have been my
sister’s 56th birthday; being with family is a good way to remember
her, although she is always with me.
Sunday July 7 - Morning
runabout, eight miles on the Leaburg canal:
This
prepares me for the main event:
I've been hanging out with this part of my family for four decades. There is now a whole generation younger than me.
I
estimate 36 immediate family members attend, and another 25-30 friends. I talk to almost everyone. Sore from my run, I still can’t resist
playing frisbee for an hour plus. Too
much cake, pie, cake, and blueberries:
It
is not too hot. There was a fly. There is some dust, but it smells of conifers
and volcanoes.
I
am tired. Sleep.
Monday July 8 – Good
bye to family, good bye to river house.
Before I even leave in the morning, Southwest lets me know my flight is
behind schedule. Same parameters as
before. I must have picked evening
flights for some reason, I forget what it was.
No matter, more time to wander north.
Route
126. This one minor two lane road in
Oregon is in much better conditioned and better constructed than most of the
roads I drove on in New Zealand. I tire
of I-5 quickly, so abandon it at Corvallis, which I’ve not visited since the
1980s. I can’t find a coffee shop, so I
continue north through Monmouth, Rickreall and Amity.
Rural
Oregon. Working lands, a true jumble of
vineyards, orchards, horse farms, tree nurseries, and other agriculture. Sort of like North Island, only less
organized in its diversity. There are
also many more pockets of wild flora, another jumble of native and non-native
species at a variety of levels of maturity.
It’s kind of ugly. I know there
is plenty of rain and the soils are great, but I don’t like looking at it. Not the narrow band of variety in the
Kimberley or in Queensland, where I could make sense of the transitions.
McMinnville. Quaint, definitely in wine tourist
country. I eat at a diner where the
server calls me “hon”. I came here to
visit the Evergreen Aviation and Space Museum. You know by now I can’t resist a good museum;
this was more on the way the than Portland Gallery of Art.
I
explore two large spaces full of lovingly restored machines, ranging from a
Wright Flyer to a 21st century Air Force drone. The main attraction however is the Spruce Goose, the
giant flying boat built by Howard Hughes in the 1940s. It is too big to photograph in toto, but I
try:
The
interpretation is good. Each aircraft
has a general history, and then a specific provenance description for that
particular flying machine. The space
exhibits gives a good overview of machines and people off the planet; it’s
even-handed and not focused on American exploits. I get a tad artsy:
Evergreen
is an interesting contrast to all the art and history I saw overseas. Most of the other visitors are guys (largely
older) who clearly love planes, and their patient families.
My
admission included an IMAX film, a National Geographic production called “Living in the Age of
Flight”. I thought this would be corny
and lightweight, but it is quite impactful.
Seeing how flight and air travel have changed the world and our
perspectives on it, as well as many familiar things – the show is partially filmed
at SFO and on a Qantas 747, and goes to many places I’ve been – times my time
over the past couple months together.
A
final museum done, I head to PDX.
Portland rush hour: it takes me 94 minutes to go 23 miles. No rush, my end of the day Southwest flight
is delayed. Plenty of time to hand off
the Son of MG to Budget, walk a couple miles in the airport and eat at my
favorite airport restaurant .
A final plane. A final
airport. My car, not a bus, train,
shuttle, or Uber. My house, finally, and
I’m really done.
How I wrote this blog - for the curious
It was fun. I
liked the creativity. I didn’t know in advance how much I’d write, but I got into it. The positive feedback helped. Thanks for that.
My main steps:
- I wrote observations, thoughts, and ideas down as possible during the day, i.e., not much on the Gibb or in Korea. Ink memory is good, particularly when there are lots of new experiences. I consciously avoided being guided by the motivation of “oh, this would be good blog material”.
- I wrote a draft, pretty much chronologically but digressing as observations and interpretations gestalted. Usually this was pretty close to final; I mentally organize pretty well in advance.
- I gave the draft one good edit.
- Uploading and inserting pictures: I mostly used pictures from my phone: while the CCD is at least an order of magnitude smaller than my DSLR, it was much more convenient due to Google Photos. Some photo editing as needed. Picture insertion was often the most annoying phase; getting the formatting to play nice over a wonky internet connection made me want to bite people.
I tried to simply describe
my experiences, thoughts/interpretations, and feelings. I rigorously
avoided adding other information, other than looking up the occasional place
name. I was not interested in telling
necessarily coherent stories. Perhaps the material organized itself that
way, given this was kind of a daily log and the proclivities of the human
frontal cortex.
I discovered that when I
wrote, or organized my observations and thoughts to be written, it helped me
comprehend my experience better. Maybe stay fresher for what was next;
there was always a next. I suppose this should be no surprise, I’ve kept
a journal for almost four decades; this was it for the duration of my
trip.
Was It a Good Trip?
Friends
have asked me this question. I of course
think about this but am confounded. A
lot of stuff happened. I went unknown places,
saw new things, new rocks, met people. I
was away, out of routine and comfort zone.
The trip was so diverse, and no particular goal, like all my past
research trips. So I have three answers. First, these experiences that
sift to the top of my mind:
New Zealand: running on the beach at Paekakariki, hiking at Tongariro,
White Island
Australia: Charnley River Station, driving on
unsealed roads
Singapore: the bachata
South Korea: the art museums, led by the Samsung
Maybe
this is an answer.
Second, I’ll invert a quote from Marvin the Paranoid Android (Douglas Adams, The Restaurant at the End of the Universe):
“The first day was the best. The second day was the best too. After that, things went into a bit of an
improvement”.
Finally, a more personal answer. As
alluded in Blog I, chunks of my reality got blown away due to family losses in
winter 2012-13. Grief and loss are part of life, but they suck. Since then, I
have felt like I’ve been inhabiting my life rather than living it. Early in this trip this shifted, I think on the drive from
Hastings to Ashhurst in NZ. The loss remains, but having travelled,
written way more than expected and taken a lot of pictures, I know I’m alive
again.
