Armchair Junk Science: The Rock Of Castle Rock

Over the last 150 years the Rock of Castle Rock has stood as the majestic symbol of the pioneering spirit of Cowlitz County. As it resides along the Cowlitz River, the Rock was used as a landmark for navigation by both the early settlers and indigenous population as they traveled North or South along the western edge of the Pacific Northwest. (Jackson 14-15)

For my Term Project for Geology 208, I took on the challenge to understand, not the recent history of the Rock, but rather the potentially exceptional geological history of this landmark and mascot of Castle Rock Washington.

The Rock of the City of Castle Rock

Located to the South of the City of Castle Rock at 46° 16’04.27”N 122°  54’25.31”W. The Rock sits along the eastern bank of the Cowlitz River. According to my GPS the elivation at the top of the Rock is 180+ feet.

Location of the Rock of Castle Rock (DNR)

The Rock also sits along side and almost attached to “Quaternary volcaniclastic rocks, tuffs, lahars, and pyroclastic rocks.” (DNR) Although the map shows the Quaternary volcaniclastic rocks, tuffs, lahars, and pyroclastic  rocks to the right and connected to the Rock. This deposit of igneous does not fully connect with the rock and is mostly a plateau along its length as it heads south and north.

On my field trip to the site I was unable to collect samples of the “Quaternary volcaniclastic rocks, tuffs, lahars, and pyroclastic rocks.” (DNR) Much of this area is covered in a thick layer of top soil and when investigating the area along the Cowlitz I found only dredge spoils from the 1980 eruption of Mt. St. Helens.

.

THE EXPECTATION BASED ON HISTORY

(DNR)

Now for the composition of the Rock itself. When investigating the surface geology of the area I used the Washington State DNR’s Interactive Geological Map on the www.dnr.wa.gov web site. It was the DNR Interactive Map that I used to obtain information on the quaternary volcaniclastic rocks that lie adjacent to the Rock. According to the interactive map the Rock is “Miocene-Oligocene Intrusive Igneous Rocks”. (DNR) This designation also includes a strip of the same Miocene-Oligocene Intrusive Igneous rock. This narrow ridge of similar rock to the Rock it self lies 2.5 miles south of the rock.

Yet the claim of the DNR that the Rock is an intrusive igneous structure was very surprising to me. Being that Castle Rock sits on top of Crescent/Siletz terranes, it was surprising to know that intrusive igneous structures could be found here. The DNR Interactive Map approximately dates the structure to 34 to 5 MA. That means the Rock was forming while this terrane was underwater through the time this entire area was finally buoyant enough to rise above the water. It makes sense that the ocean crust under Castle Rock would have gone through thrusting from the extra ocean crust and sediments being jammed beneath it from the newly sub-ducting Juan De Fuca Plate (Dawes) that could have created fissures and faults. (Roberts 38) Then there was also the Compression of the Juan De Fuca Plate sub-ducting underneath the Crescent and Siletz terrane that formed the Cascade mountains.  (Alt 172-173) Also the Rock would have formed in the ocean sediments that have now eroded away. How extraordinary the idea that there was enough ocean sediments here to keep rising magma from erupting at the surface.

Before I left to investigate the Rock I was expecting to find gabbro or perhaps a peridotite deposit at the location. Both best fit the the definition of an intrusive igneous for this area. Or at least that is the conclusion I had come to. Personally I was leaning to towards the idea of the Rock being made out of peridotite. This should be a reasonable expectation because “intrusive igneous rocks such as diorite, gabbro, granite and pegmatite that solidify below Earth’s surface.” (geology.com)

“No Trespassing”

I first began my investigation of the site “Miocene-Oligocene Intrusive Igneous Rocks” (DNR) south of the Rock I was met with a Cowlitz County Utility “No Trespassing” sign.  Choosing to adopt ethical specimen collecting, I decided to heed the sign and not trespass for this project.

.

Exposed rock on the north side of the Rock.

It was then decided by me, myself, and I that specimen rock collecting should be relegated the the location chosen for the term project. The picture to the right is an exposed outcropping of rock on the flank of the Rock. As can be seen in the picture the outcrop is composed of small blocks of what appear to be igneous in origin. With careful prying I was able to collect a small sample.

.

This exposure of rock on the Rock was my second collection site at the Rock in Castle Rock. Located on the western flanks of the Rock, this exposure has some larger blocks of rock. I was able to collect a specimen with some effort from this site.

.

.

.

Just 50 feet from the second collection site I was able to scramble onto the edge of this section of rock just left of center of this picture. This outcrop of rock is quite solid compared to the rest of the crumbling rock exposures on the Rock.

.

This solid outcrop is so stable this anchor point has been drilled into one side of this mass of rock. There was an attempt to collect a specimen from this site yet the rocks here proved to be so stable I was unable to remove a sample.

I attempted to scale the Rock to find more specimens to collect. On my way up I noticed that the Rock is covered with a thick layer of topsoil and what rock that was available at the surface to collect was most likely transported there to build up the trails on the Rock. Not wanting to disturb this historic monument of the proud peoples of the City of Castle Rock, I left the soil undisturbed.

The Rock-Sample “One”

Using newspaper as a scale reference I began taking pictures of the top rock (specimen #1) in this picture. This specimen measures 15 to 18 millimeters thick and is approximately 10 centimeters wide. My initial impressions about the rocks I was collecting  not exhibiting characteristics of intrusive igneous rocks was made very obvious when examining this sample.

.

The Rock-Sample “Two”

It was all to clear by the time I made an even closer examination of specimen two. Specimen two is a 5 x 10 mm chunk of basalt. There is nothing peridotiteor or granadiorite about either of the two specimens I collected. Rather both specimens are very black and are fine grained. Even with a jewlers loupe I was unable to distinguish the specimens I collected from the Rock from other examples of basalt from the local area.

.

After determining my samples as basalt I contacted my sister in-law whom possesses a degree in geology. I asked her to examine my specimens independently. I made sure to not let her know what my conclusions were from my observations of the specimens. When my sister-in-law was able to examine the rock specimens from the Rock she took but a moment pause and said “It’s basalt. So what do you wanna know?” I explained to her my findings with the Washington DNR Interactive Maps. My sister-in-law then immediately asked to use my computer to search the USGS website for corroborating information. After taking over 30 minutes to search or more information she concluded she was unable to find any information about the Rock online and was amazed I found as much as I did. After doing my own research the USGS mostly had water data about the Cowlitz River in Castle Rock. Ever since the day I picked the Rock in Castle Rock as my field site I have been trying to access the USGS geologic map of Castle Rock with little success. This has made my search for corroborating information from a reputable scientific organization far more difficult.

Washington State DNR

Undaunted by the lack of information, I turned to the source of my apparent bogus information about the Rock being intrusive igneous. I first fired off an email to the Washington State DNR to get some clarification on the classification of the Rock. I did not receive any response. I then found a general information e-mail address and received a response stating that my email had been forwarded the Geology & Earth Resources Division. As of the writing of this term project I have yet to receive a response to my e-mail.

The Rock-Sample (two) & Delameter Creek-Granite Sample

This image contains the number two sample from the Rock and a specimen of  granite from the Delameter Creek in Castle Rock. The Delameter Creek granite sample is what I would have expected to find when collecting samples from the Rock or perhaps peridotite would have been a better and more reasonable find at the Rock

Delameter Creek bi-valve fossils in sand stone

The map above depicts the location of the samples from both the Rock and Delameter Creek locations. Its a personal curiosity why someone is able to find granite in a creek that cuts through “Quaternary alluvium, dune sand, loess, and artificial fill” (DNR) and not apart of a rocky outcrop that is supposedly intrusive igneous.

.

The Hypothesis Based On My Findings.

 The samples I have collected are just simply not what I have learned to be the mineral types expected from intrusive igneous rocks. Given the information I have found about the the Rock being a plutonic structure and my finding when analyzing the samples collected,   I have generated a hypothesis.

Stratigraphy

Approximately 25 to 20 Ma the Juan de Fuca Plate began to sink into the earth and apply pressure against the the oceanic slab of the Crescent/Siletz terranes. This compressive force began to slightly deform the crust of the Crescent and Siletz terrane. At this point of Washington’s geologic history the Juan de Fuca plate had not reached far enough beneath Crescent terrane to infuse any rising magma with large amounts of dissolved gasses. The oceanic slab that western Washington now site’s on was still very moist in spots and this lowered the slabs melting point on those areas. The slab beneath Castle Rock started to melt. In combination of compressive forces of subduction and melting of the slab under Castle Rock the magma slowly made its way through the Crescent oceanic slab. As the magma came in contact with the ocean sediments above the slab the magma began to cool rapidly. This fast cooling close to the surface would be considered a hypabyssal igneous intrusion. Being that the intrusion was close to the surface, in moist ocean sediments, and being a small volume of intrusive magma; the cooling of the magma was rapid in terms of intrusive magmatic events. Such rapid cooling would prevent course crystallization of minerals found in a typical intrusive igneous structures. The Rock was exposed over time from erosion caused by the Cowlitz River as it cut out the valley it now flows through revealing a plutonic structure. Given the crumbling condition of much of the exposed rock, it is possible as much as 1/3rd or more of the original plutonic structure has been eroded away.

How To Make Somone Sound Like An AssHole: The Eulogy

“This is not one of the funerals I’m looking forward to.” ~A Friend (2006)

WARNING! A Dead Asshole Contained Inside

I have been either fortunate or unfortunate to have gone to many funerals in my 34 years of habitation on this planet. There is one striking and familiar constant with them all. The people giving the eulogy make the formally living person sound like some asshole! In all, every eulogy I have been to sounds just like the last one.

Eulogist:

Since (Insert beloved asshole here) passed on to the great expanses of a place far better than this shitty hellhole. We have all grieved heavily and are unable to figure out how to go on with out (Insert beloved asshole here). But we will try our best to continue on without him/her the best we can. Because our entire existence had to revolve around (Insert beloved asshole here). Yes, we must carry on and live like sick wretches without (Insert beloved asshole here) to guide us through

There should be a self-help book called Be a Better Person: Die. I know of at least three people who have died that had little resemblance to the mythical champion and hero the eulogist portrayed. I have witnessed people who were cheated, screwed over, and left in ruin by the departed make extraordinary claims about the dead asshole’s integrity in their eulogy.

For me I want to be remembered like a true asshole. So based on the funerals I have attended, I feel I need to break the mold of the typical funeral. I want my eulogist to let everyone know all the terrible things about me and for good measure make up most of those terrible things. Ex. “David was a buggering asshole who had a fetish for hunchbacked midgets and Otterpops.”

How better to be remembered then to have a funeral that is more like a comedy roast than a commiseration seminar/meeting. For years people would talk about my funeral and how it departed from other funerals they have been to. So be remembered and really insist on a tasteless eulogy.

Racist Article by Eleanor Roosevelt

On May 20, 1954 Eleanor Roosevelt wrote an article addressing the U.S. Supreme Courts landmark ruling on Brown vs. Board of Eductaion. In a misguided attempt to reach out to the formerly segregated black masses; Eleanor wrote an article strewn with what she called “jive speak“. As you can guess, editors refused to publish such insensitive dialog and convinced Eleanor to reword her article before publication. You can find the published article HERE.

For you, I have obtained this rare and incredible original article written by one of the most influential women in American history. I hope you will not see Mrs. Roosevelt as insensitive or a racist. Rather, I would have you look upon me as being bored with too much time on my hands.

NEW YORK, MAY 20, 1954 –

I wuz chillaxin’ on da “Tex an’ Jinx Show” I wuz given da news o’ da unanimous Supreme Court decision dat blasted segregation in da skools. I be bangin’ dis here wuz uh unanimous decision cuz I th’o’t it will be a bee-atch fo’ da states wiff segregated skoo systems ta hold out against such uh ruling. So dis be a big dilly!

If it wuz not fo’ da fact dat segregation in itself be a bitch slap, da old rule o’ giving equal facilities might gots gone on satisfying our sense o’ justice fo’ uh long tyme. It iz very difficult, however, ta ensure real equality under uh segregated system, an’ da mere fact dat ya cannot move freely anywhere in yo’ country an’ be as acceptable everywhere as yo’ neighbor creates an inequality. Peep dat shit!

Cletus always bring up da queshun o’ marriage between da races, an’ I realize dat that iz da queshun o’ real concern ta peeps. It just be ol’ about haten da jungle feeva’. But it seems ta me uh very personal queshun which mus’ be settled by peeps in da hood an’ by da development o’ da cultural an’ social patterns within uh country. Whitey can nahh longer lay down rules as ta what individuals will do in any area o’ they lives in uh world dat iz changing as fast as ours iz changing taday fo’ shizzle. It be blunt time-pull out your philly…

The Schwarzenegger Amendmendment

No matter what your political bent might be, amending the Constitution to allow Arnold Schwarzenegger to become president would simply kick ass. He is this big intimidating cartoon like guy that also says the most screwed up and absurd cartoon things. Here are some examples from his term as “Governator” of California.

Examples:

“To those critics who are so pessimistic about our economy, I say, Don’t be economic girlie men!” ~Gov. Arnold Schwarzenegger

OR

“She’s either Puerto Rican, or the same thing as Cuban, I mean they are all very hot. They have the, you know, part of the black blood in them and part of the Latino blood in them that together makes it.” ~Gov. Arnold Schwarzenegger

Just imagine during high level security meetings with foreign dignitaries and Arnold leans over to Sweden’s Crown Princess Victoria and says “I can look at a chick who’s a little out of shape and if she turns me on, I won’t hesitate to date her. If she’s a good f**k she can weigh 150 pounds, I don’t care.” <—(Another actual quote.) Would that not be SNL GOLD?

You remember the days of stupid quotes from Bush Jr.? I miss that kind of inane b.s. coming out of our most powerful leader. Here are some examples of what to expect from President Schwarzenegger.

“I think that gay marriage should be between a man and a woman.” ~Arnold Schwarzenegger

“Having a pump is like having sex. I train two, sometimes three times a day. Each time I get a pump. It’s great. I feel like I’m coming all day.” ~Arnold Schwarzenegger

“My relationship to power and authority is that I’m all for it. People need somebody to watch over them. Ninety-five percent of the people in the world need to be told what to do and how to behave.” ~Arnold Schwarzenegger

Arnold would be an endless source of the best inane b.s. a nation might want or need. I bet our old buddy President Mahmoud Ahmadinejad would think twice about refining even just another milligram of weapons grade uranium with a president in the White House saying things like:

“I like the color red because it’s a fire. And I see myself as always being on fire.” ~Arnold Schwarzenegger

In conclusion, I hope I have made my case for a President Schwarzenegger. So lets continue to be the self-destructive country that we are and amend our Constitution!
