Being Transgender: On Gender Dysphoria, Biology, Evolution, Human Survival, and a Look at One Person’s Story

Leave a reply

Yesterday, our local book group met to discuss, “Tall Annie: A Life in Two Genders”, with its author and her husband of 18 years. The book is about her often painful, very personal, story of growing up with gender dysphoria, a recognized condition now, but not then, in which a person is born with the genitalia, the physical features of their sex, in conflict with their own gender identity, how they see themselves. These are two separate qualities, one’s physical sex and one’s gender. I won’t get into how one’s physical sex can be intergraded, except to say that an individual, every individual, is born along a continuum between the two poles of being, female and male, some individuals born intersex, with neither male nor female fully formed genitalia, genitalia that may only be partially functional. We are each more or less male or female. Sex and gender are not a simple either/or questions. Continue reading →

From 0’ – 3,000’ in 70 Million Years:  Building Oregon, Dry Canyon, The Shaping of Redmond and the Geology of the Paleo-Deschutes, Part 3

Cascade Volcanic Arc –

Over the last 2.5 million years, roughly corresponding with the Pleistocene Ice Age, there have been at least 1,054 volcanoes in a ‘belt’ from Mt. Hood running 210 miles south to the California border and then, after a break, continuing to Mt. Shasta and Mt. Lassen, in a band 16 to 31 miles in width. These latter two, southern most of the Cascades, show no effect of glaciation from Glacial Periods. They were far enough south of the Glacial Ice to be unaffected. The material ejected and flowing from these many volcanoes and vents come from the crustal material of the subducting Juan de Fuca plate. The Cascades are a defining feature of our region in terms of aesthetics, but also as a shaper of climate, as well as being a physical barrier limiting the movement of organisms and thus goes to determining the ‘shape’ of our lives here. The Arc is still active, magma is still being ‘delivered’, building incredible pressure below through these same processes which have shaped this place to date. While we may assess its various mountains as ‘active’ or not, the volcanic arc, is still very much a factor in determining our long term future. Where it will next erupt from, and what form that will take, is impossible to say within any degree of confidence. But the earth’s tectonic plates are still in movement. Magama is still slowly, but inexorably, coursing through its crustal layers and the movement and pressures will continue to result in further eruptions. Continue reading →

Clarno Formation – 54 to 39 million years ago.

Getting back to Central Oregon, the Clarno Formation formed much of the region’s base rock, an accumulation of volcanic rock, their sediments and soils in layers to as much as 6,000’ thickness. 6,000’. The area was what geologist call an ‘extensional basin’, a broad low basin between the Blues and Wallowa Mountains and the accreting and volcanic landscape forming to its west.

As the Clarno was forming so was Siletzia off the coast of Oregon, Washington and British Columbia, building up relatively rapidly from intense and volcanic activity between 56-49 million years ago to the west. Siletzia was then accreted to the continent due to plate tectonics. In Oregon this terrane became the area we now recognize as our Coast Range and Willamette Valley.

This area looked far different before this period than at its end. It looked far different again, from when it attained its maximum elevation, to how it appears today. Trying to tack all of this is a bit like trying to follow a 3 ring circus…with many more rings, all proceeding at the same time, with generous overlaps. When looking at our landscape we are faced with the problem of the never ending processes of ‘addition’ and erosive ‘subtraction’. The ‘end’ of the period we define as the Clarno Formation is not one of some final result. The regions canyons, have today been deeply eroded, cut steep, with broken slopes, below the rim tops we see today. These were very different 39 Ma and they will look far more different in another million or ten million years from today, likely unrecognizable to us. Even if we were able to somehow survive until then to observe them, our ‘snapshot’ and pliable memory of them would have likely transformed over the many centuries. Erosion will have been at work over the intervening time together with those forces working to ‘build’ and ‘lift’, the working of plate tectonics locally continuing to drive the process as they continue in their slow motion crashing, transforming the surface from below.

During the Clarno those forces continued with, explosive eruptions, lava and pyroclastic flows, lahars that poured down from volcanoes of the Mutton Mountains in the formations northeast corner and Ochoco Mountains area, just west and south of the Blue Mountains, along with their mudstone, and conglomerates derived from the erosion of both accreted terranes and that of volcanically ‘built’ structures. And thus was ‘built’ the Clarno and the later John Day Formation. The three largest volcanic structures of the period in the Ochocos remain today as the Crooked River, Wildcat Mountain, and Tower Mountain Calderas. These volcanos have not been active for many millions of years. The center of volcanic activity in the region began to shift westerly during the Clarno with the tectonic changes accruing to the expanding continent’s edge developing into what would be the Cascade Volcanic Arc. The Ochoco Volcanic Area remained an active factor on through the development of the John Day Formation Period. Continue reading →

John Vaillant’s, “Fire Weather: A True Story from a Hotter World”

Leave a reply

‘Global warming’ and ‘climate change’ have become trigger phrases, hot buttons for millions of Americans. What were originally coined as descriptive, short hands to signify a complex climatological process induced and accelerated by human action, has been thoroughly politicized. Today they separate ‘us’ from ‘them’.

For those on one side, the earth, is a closed, limited and complex system we are ‘pushing’ beyond its inherent abilities to maintain dynamic balance within margins which organisms can live in a vital, healthy state, biological processes continuing in a familiar manner. This ‘side’ understands that we are adding vast quantities of carbon to the atmosphere causing the earth to retain more heat, heat which ‘spins’ the entire system faster, potentially beyond the limits that life evolved with. Such a more ‘carbonized’ atmosphere resembles that here of many millions of years ago, of a warmer earth, that was nonsupportive, too warm, for the vast majority of organisms which exits today. Too much carbon released into the atmosphere? These effects are easily demonstrable in a lab experiment. These people have some understanding of what they must do to slow and halt these changes, what we must do  to ameliorate the damage we’ll inevitably face. Pushed too far the system won’t return to the old ‘normal’ in a few weeks, months or years. It will be with us for generations to come.  Continue reading →

The Gene: An Intimate History, a Review

Leave a reply

I finished reading Siddhartha Mukherjee’s book from 2016, “The Gene: An Intimate History”, a dense, engaging book, written in a prose style, conversational, thorough, accessible and personal, exceedingly rare qualities to find in a book covering such technical topic. Mukherjee, trained and worked as an oncologist, won the Pulitzer Prize for his earlier book on cancer, “The Emperor of all Maladies: A Biography of Cancer”. He is currently an associate professor of medicine at New York Presbyterian Hospital/Columbia University. Understood to be the ‘best’, or most complete and thorough history of genetics, our understanding of it and the ethical questions of its increasingly influential applications in medicine, society and evolution. Of such broad scope in the changing landscape of medicine and its science, it has expectedly, become subject to an array of criticisms. The practice of science is not perfect. Our understanding is forever evolving and as much as promoters might insist that theirs is solid and fixed, our knowledge will always be imperfect. We circle around a topic, defining it closer and closer, but never quite understanding it fully, questions leading us to more questions, our knowledge shaped by what we already ‘know’, and very occasionally propose entirely new ways of explaining, new theories, that dislodge previous established theory.

The Much Maligned Western Juniper: The Role of Juniperus occidentalis in Central Oregon

Leave a reply

Old growth Junipers near Cline Buttes. These two rooted down long ago on top of this lava flow. Much of the lavas here were produced during the Deschutes Formation over many thousands of years more than 5 million years ago. Surface lavas, cliffs and slopes define the area with a few sediment filled basins dominated by Sagebrush and Bitterbrush.

The Western Juniper is the  singular native tree of Dry Canyon and the immediate Redmond area. I grew up with it here in Central Oregon. When we moved here in ’61 i remember driving north after passing through miles and miles of various Pine forests, which eventually yielded, riding in our VW bus, as we left Bend. Bend sits within the ecotone, the relatively narrow transition zone, between Ponderosa Pine forest and Juniper steppe. What were these trees? Coming from California’s Salinas Valley, the landscape could hardly be more different to a six year old. So different in form and detail, Junipers squatted darkly across the landscape, nothing like the tall, majestic Pines or Oaks I was more familiar with or even the Lodgepole Pine we drove through across the pumice plain of the LaPine area.

Origin Story: The Trials of Charles Darwin, A Review

Leave a reply

Evolution, natural selection and Darwin are often triggers for many conservatives. On their announcement people will often enter into angry diatribes which nearly just as often sets off others into a defense of shared ancestors, adaptation and descent, sometimes with a reciprocal attack against a determining role for God. It quickly moves into a polarized argument, one side embracing a christian, all knowing and powerful God who created all things in their particular ‘fixed’ forms, with man in God’s ‘image’, railing against those who would have us descending from monkeys, as if one day a monkey simply ‘birthed’ a modern human, an idea that completely ignores the substance of Darwin’s theory. The public argument seems to remain the same despite the passing of decades with little change, the battle lines firmly established, arguments entrenched. So, it is interesting to read, “Origin Story: The Trials of Charles Darwin”, by medical doctor and author, Howard Markel, which came out earlier this year, 2024. This divisive, get nowhere, pattern was set from the very beginning. Continue reading →

Climate Change and the Limits to Life: a couple reviews and examination

Leave a reply
Not to ‘rain on anyone’s parade’, but walking home last night at 10:30 from a neighbor’s, the air was still, it was 81F and 51% humidity…ugh. Normally, it cools off significantly here in the high desert once the sun goes down. This summer is different.
Today, August 2, we’re forecasted to break 100F again. That will be the 26th day over 90 this year, the ninth over 100F…with less than 1/4” of rain since June 1. I’ve mentioned before that our average high temp for July is 85F. We were at or below that only four days in July.
Our old normals no longer hold. They are shifting consistently higher from year to year. This is happening worldwide. Its effects are greater, and more devastating, at equatorial latitudes and polar.
It is estimated that at or above a wet bulb (W/B) temperature of 35C the human body cannot cool itself. We cool down by evaporating away sweat on our skin surface. W/B temps mimic this by placing a wet cloth sleeve around a thermometer bulb, the evaporation taking away heat in the same way. W/B temps are then cooler, ‘chilled’ by the water evaporating away, drawing heat away from the thermometer’s temperature sensitive bulb, than ‘dry bulb temps. When these rise higher than W/B 35C, our internal organs and systems begin to falter and will fail in relatively short order, depending on our state of health. Some of us will have greater tolerance than others, but all will die at these levels if they have no way to cool their core temperatures. Some argue that this begins happening below this. Many areas are already experiencing such ‘events’. Governments are still slow to act We continue to build out our cities in patterns that maximize energy use and consume resources and products from around the world which must be transported to us, removed from where they other wise occur. Profit driven businesses, still refuse to change their practices and goals, insisting that the market will solve this…the same market that has created the problem…and we ‘demand’ this, these patterns, goods and services, ever more ‘divorced’ from the places we actually live, the limits and constraints with which we’d otherwise have to live.

On Healing: Life, Place and Relationship in Oregon’s Great Basin Country

Leave a reply

The massive fault block of Hart Mountain, Poker Jim Rim in the distance to the north. The gravel county road switchbacks up the more than 3,000′ beginning from the center in the distance here. From here this is how you get to Steens Mountain without doing miles of backtracking.

I woke up this morning to the sound of bird song…nothing else. There were Western Meadowlarks and a multitude of others, I’m sorry to say I don’t know, but beautiful and distinct. I was laying in bed, atop our truck, thinking about how rare an event this is for so many of us…not that the birds aren’t here greeting the morning every day, but that so many of us aren’t ‘available’ to hear them, sequestered away safely in our homes, otherwise occupied or, more commonly, the birds literally excluded from our urbanized and ‘modern’ places of residence, their own places developed/destroyed. Entire neighborhoods and cities excluding all but the most common songbirds and passerine species.  Little quarter is afforded most wildlife in modern development…and that upon which their lives depend.  Continue reading →

Notes on Complexity: A Scientific Theory of Connection, Consciousness and Being, Thoughts on the Book

Leave a reply

[My ‘reviews’ are not strictly book reviews. I’m not trying to distill the author’s ideas down into a simpler ‘bite-sized’ piece or discuss their ‘style’. These are my thoughts after having read these books. My attempts to make sense of them, usually after several rewrites, as I work to fit them into what I already ‘know’, an attempt to make the ideas presented in this book, consistent with those which I’ve read by other authors. They include ideas not covered by this author. Rarely, if ever, can you come to an understanding from a singular perspective. This is a link to an annotated bibliography on my Blog of several of the more significant books which have  influenced me on this topic,]

Complexity theory? Do we need a theory to determine what is complex? No, that’s not what this is about. Theise’s book does not layout a system for determining what should be considered complex/complicated or not. This is a book about systems and structures in nature and how they come about. He discusses how mainstream science has fallen short in explaining this and why, the author believes, without changes in approach, we will continue to fall short. He goes on to present an alternative, or, rather, a ‘sister’ approach which can provide a previously excluded way of ‘knowing’, and in so doing, can account for the ‘gaps’. The problems are not just that this is a difficult concept to understand, but that at the most basic, quantum, level, that at which nothing can be divided smaller, where all things ‘begin’, actions and processes do not follow human logic and contemporary expectation….

I remember reading the book “The Limits to Growth” in the early ’80’s, which introduced me to ‘systems theory’, an approach which required looking at all of the parts and actions within a system, consider their relationships and how they work together, in order to understand its ‘working’. A system could be ‘modeled’, mathematically and the long complex equations run on a computer. There were generally multiple possible models to run. This gave us a degree of ‘predictive’ power, but these would always be approximations, because no model could be perfect and every situation, every starting point, would result in a somewhat different ‘answer’.  I followed this with James Gleick’s book on Chaos Theory and its ‘ability’ to explain certain types of patterns, which appear spontaneously in nature, while introducing me to the idea and maths of ‘fractals’. There were multiple  books on ecology which necessarily take a wholistic approach. James Lovelock and Lynn Margulis, published their book on Gaia Theory, a product of their collaboration which began in the 1970’s, a theory of the Earth itself functioning as a self-regulating system, as if it were a gigantic, single, organism of which we ourselves are a part. All of these were related, coming out over a short span of years. These were ‘new’ hypotheses and theories, never before seriously considered by science back then, but now being investigated, their validity, and the answers they suggest, impossible to ignore.

Science often advances this way. Seemingly radical ideas, rejected by the majority of the mainstream…until resistance worn down, their validity demonstrated through thoughtfully conducted and reviewed experimentation, the scientific community then coming around to more broadly adopt them and reshape science and our understanding. (Some argue that this ‘process’ requires some number of the old guard to literally die, younger minds being more free to consider the new.)  Margulis and Lovelock’s ideas were just too far out there for most at the time. For many, such thinking then belonged to the realm of metaphysics, or fanciful science fiction, frivolous exercises in thought and belief. Exploring these ideas, testing their validity, only became possible with the computational capacity of ever more powerful computers and an openness to branches of thought once rejected by science. ‘Game Theory’ and cybernetics played a role in all of this as well. Complexity Theory has far more capacity to explain how matter and functional systems emerge, or manifest, than mainstream science could historically. Nature, through the conditions and forces in play at any given moment, ‘drive’ the universe toward order along with the ‘creation’ of complex structures and functions, at the cost of energy spent, ‘held’ in the new structures and dissipated away as lost heat. All of countless processes linked to one another through a myriad of relationships and the feedback loops which comprise them. The universe continues to evolve, and as it does, it continuously spins off everything in it, from sub-atomic particles to human beings over time, a process which it itself is directly influenced by its evolving ‘self’.
