Becoming Native to This Place. More.

Four Native Plant Master classes educate new learners in Colorado’s fauna: one for the high plains, one for the foothills and one for the montane eco-system where we live. The fourth, plant sketching, will support the nature journal I’m starting this week.  The Friends of the Colorado Geology Museum offers lectures and field trips that focus on Colorado’s physical features. Geology Underfoot, an excellent geology primer on the Front Range, suggests 20 self-guided field trips to see instances of particular developments over geological time. Wild Food Girl presents opportunities to hunt food in the Rockies.

How to saturate myself with the Old West, the mining and ranching histories here, that’s a challenge that lies ahead though History Colorado provides opportunities.

It’s an exciting time, full of information. Lots to do.

 

The Rio Grande Rift

Imbolc                                                Black Mountain Moon

Into the Colorado School of Mines last night, its Museum of Colorado Geology, for a second lecture to the Friends of the Museum. This one: Whither the Rio Grande Rift?

The significance of the title escaped me until Vince Matthews, former Colorado State Geologist, explained that the rift was a spreading of the earth’s crust, a spreading that thins the mantle and increases volcanism and creates faults. Then it hit me. Oh, a rift. Like the Olduvai Gorge in the horn of Africa.

There are three faults within the Colorado portion of the Rio Grande Rift that made it onto the USGS hazards map, one believed capable of producing a 7.5 magnitude quake and another of producing a 7.0 quake. Logarithmic scale. Those would be powerful and they would come in the middle of Colorado, toward the New Mexico border.

He used two terms in this dense, finely argued lecture that were completely new to me: graben and lineament.

Graben: In geology, a graben is a depressed block of land bordered by parallel faults. Graben is German for ditch or trench.

 

Lineament: A lineament is a linear feature in a landscape which is an expression of an underlying geological structure such as a fault. Typically a lineament will comprise a fault-aligned valley, a series of fault or fold-aligned hills, a straight coastline or indeed a combination of these features.

The focus of his presentation was the true northern extent of the Rio Grande Rift. Here’s a map that shows its extension in the consensus view (more or less). In this map you can see the Rio Grande rising in southwestern Colorado, then flowing through the San Luis basin into New Mexico and then onto its more familiar location as a major boundary feature between the US and Mexico.

Vince said that current thinking took the Rio Grande Rift as far as Leadville.

 

Leadville in this map is the first black lettered city above the C in Colorado. I use this map to show you the San Luis Basin (the light tan opening to the left of Highway 25 and starting at the New Mexico border. The San Luis Basin is a major feature of the Rio Grande Rift as it comes north out of New Mexico.

Matthew’s argument extended the Rio Grande Rift considerably further north and then hypothesized a turn from its primarily north/south axis to an east/west one. This map of the Colorado Plateau can be used to illustrate his argument:

 

Matthews extended the boundary of the Colorado Plateau east to include the Rio Grande Rift, then proposed that the rift extended east/west toward the area here marked as the White River Plateau. He based his argument on indicators of a rift zone (which I won’t go into here) and on an experiment on a clay model of the Colorado Plateau.

In essence he argues that the Colorado Plateau is a tectonic feature that has been rotated clockwise. When asked how that could have happened, he said, “I don’t know.” But, if you imagine the Plateau as a piece of the earth’s crust that has physical integrity, then a motion pushing up on its southwestern edge would turn it clockwise. One of the other geologists in the room proposed the San Andreas Fault as it developed. (I got lost right here, but I followed the argument up to this point.)

Very interesting. These lectures are helping me orient myself to the unusual topography of Colorado and some of forces that shaped it.

BTW: I loved Matthew’s description of two cinder cones as “very young.” They were only 640,000 years old. Puts 68 in a very satisfying context.

Living in the Long Now

Imbolc                                                 Black Mountain Moon

Between now and the time when Pipe Creek fills the lake that will cover all of human artifice here on earth there is a long interim. It may well be that humanity will fan out from this planet, seeking a home somewhere in space, perhaps on Mars or a moon of one of its sister planets, perhaps even out beyond the Oort belt, the furthest reach of Sol’s solar wind. I cannot see that far and, though I hope it turns out to be our destiny, I do not rely on such exploration in considering how far I can see.

We know from astrophysics that in about 7.5 billion years the sun will expand in its red giant phase, its bulk then extending past our orbit. That is a sure and certain end to the planet. Before that, though, several other extinction events loom. This brief Wikipedia article outlines several of them.

These future disasters (from a human perspective) limit the time of human habitation on earth, not by theological fiat, but by the laws of physics. In that they represent the working out of fundamental laws of this universe they are neither apocalyptic nor commentary on human failing. There are future disasters, perhaps of an extinction event level, that might have the human fingerprint, yes, but even these only advance the end of human life on earth, a certainty in any case.

Considering this certainty without placing an exact time frame upon it, we can then work backwards to consider faith, positioning ourselves in the world, however broadly you may define that term. We live in the long now between the emergence of life on earth and its end. Humanity is an extension of that true miracle, that enduring mystery, life’s creation ex nihilo from chemicals inert, as far as we know now, since the very birth of the universe.

Over our evolution, lengthy from the perspective of our species, but a wink in the time since earth’s creation we have developed into an animal capable of reflecting on its fate. That’s what I’m engaged in here. Does our fate really matter? Yes and no.

No because our duration as a species on earth has limits, ones we can define and foresee, even if we can not predict those limits exactly. Yes because our need to know ourselves as part of the universe, as part of life on this planet seems to be a human universal, most likely triggered by meditation on our own, individual limit: death.

If we accept (and you may not), that this world is wonder enough, miracle enough and, further, that any next world, no matter what its shape and character might or might not be, is hidden behind the pale of death and the inescapable veil created by our senses, then we must consider how we fit into that long now currently underway, the one between the creation of the earth and then life upon it and our emergence, and that certain end to this planet and its life which physics demonstrates.

That consideration will be the content of the next post in this series.

 

OK. Wow.

Samain                                                                      Closing Moon

This just posted on the NYT:

“The Philae has landed.

The European Space Agency’s ambitious attempt to place a spacecraft on the surface of a comet succeeded when a signal arrived at the mission control center at Darmstadt, Germany, just after 5 p.m . local time (11 a.m. Eastern time).

Cheers erupted.

“We’re there and Philae is talking to us,” said Stephan Ulamec, the manager for the lander. “We are on the comet.””

Something’s Happening Here

Fall                                                                                       Falling Leaves Moon

50008 28 10_late summer 2010_0199I’m having these flashes of insight, as if some larger realization lies not far from view, but still below the horizon of awareness.

Raspberries have something to do with it: wading into the thorny brambles, canes curved low with hanging fruit and picking off the sweetness. So do those blue skies and the chill in the air while I engage in the oldest human method of obtaining food-gathering it from plants.  That symbiotic trade between the food value of the fruit and our inadvertent willingness to bear its seeds to a new place places me there, so firmly there. No where else but picking raspberries.

I will say it with caution, because I don’t want to be confused for a transcendentalist, but I do look into the raspberry when I pick it. But, I also look into myself. When I look into the raspberry, I see water siphoned up from the soil, having fallen in rain or come sprinkled in from the aquifer below our property. I see colors, beautiful and rich, each fruit a miniature, reminding me of those Persian paintings. The seed is evident there, encased in a small cell filled with water and nutrients, so that when it hits the ground it will have what’s necessary for a healthy transition from top of the plant to the soil which is its natural home.

The raspberry itself is the Great Wheel, all of it. It comes on the plant after Mabon, after Michaelmas and left on its own will fall to the ground, probably before Samain, where it will lie on or just under the soil through the cold months of Winter and the days of Imbolc. Sometime in Spring it will begin to move, to thrust a small green stalk toward the sky and another, darker filament into the ground, seeking stability and food for its above ground presence. Over the course of Spring and Beltane the stalk will grow and the root deepen and strength its grip on mother earth. In the heat of Summer the stalk will grow into a cane, thorns will pop out and leaves, all moving fast toward the sky, the sun. Then it will reach Lughnasa and the strength of the cane and the roots will be at their optimum, ready to press out on tiny branches, flimsy and delicate, heavy dark-red fruits which will, once Mabon is past, once again droop toward the ground.

And so in the raspberry is millions of years of evolution, an evolutionary path older even than the one we humans have made, an ancientrail indeed. When I see the raspberry, this is what I see. When I look through the raspberry, I do not find revealed another metaphysical layer, a layer transcending the mundane and making it somehow special. No, I find the story of this stuff, these elements, this reality, a story which spans billions of years for this universe (and who is to say how many universes there are?), a story which spans millions of light years of space (and who can say how many miles there are in places we cannot see?).

If I wanted to introduce the religious into this conversation, I would tend toward the Hindu pantheon with Brahma the stretched out space in all its extensions and Shiva as the creator and destroyer of worlds and universes and maybe I would add in Vishnu so that this time in which I exist has an image of stability and permanence, even though such an image is an illusion. For which there is, of course, a wonderful Hindu idea, Maya.

I find Brahma, Shiva and Vishnu only useful as metaphor, as analogy but I do find them valuable in that way-as stand-ins, avatars, for the mystery that is what all this is.

These flashes, just out of sight. Something’s coming. And I’m satisfied to wait on its arrival.

Blood Moon Risin’

Fall                                                                                   Falling Leaves Moon

 

Add blood moon to the adjectives in front of the Falling Leaves Moon for October 8. These lunar eclipses reflect light from sunrise and sunset giving the moon a russet color. Blends in well with the changing leaves. On my weather station I notice a small symbol I’ve not seen for awhile. A snowflake. Means it could snow.

We’re going to make use of the cooler weather with a work outside day today and perhaps a couple of other days this week. First task, start a fire in the firepit so the laborers can warm themselves. Then, the harvest. After that move old aluminum siding to the garage for recycling. Yes, this is stoop labor.

Gotta get out there.

The Original Pentecostal

Fall                                                                                   Falling Leaves Moon

Listen to the languages calling out to you. From the lilac bushes, from the way vehicles move on the freeway, from the body movements of people in a crowd, of the clouds as they scud overhead or stop, gray and wet. Watch dogs as they wag their tales (tails, I meant, but I like this homophonic error) or smile or lean in or bark or whine. Watch their eyes move. Babies reaching, reaching. From the insects as they buzz the late season flowers, the wasps flying in and out of their nests, the birds high in the trees or walking across the road. The turtles when they walk miles to find a proper place to lay their eggs. So many tongues.

Mother earth is the original pentecostal, speaking in so many tongues. She also speaks in the movement of continental plates, the upwelling of magma, the process of evolution, the deep sea vents and their often alien seeming life forms. Or look up. Into the milky way and see the language of origins spread out before you on velvet, the most valuable jewels in all of creation. Each of these languages has a syntax, a grammar, meaning. The speakers of these languages want to reveal their purpose.

But we have to have ears to hear. Listen.

(Pentecost, El Greco, 1596)

 

Mabon 2014 and the Springtime of the Soul

Fall Equinox                                                                      Leaf Change Moon

Today the earth’s celestial equator (the earth’s equator projected into space) passes through the sun’s ecliptic (the sun’s apparent path throughout the year, actually caused by earth’s orbit.) You usually hear this put the other way around; that is, as the sun passing through the earth’s celestial equator, but that represents the stuckness of paleolithic astronomy that assumed the earth was the center of the solar system. From the diagram above you can see the sun’s declination (degree above or below the celestial equator) is 0 on the vernal and autumnal equinoxes.

This same diagram is very clear about the solstices, too. You can see that when the earth’s orbit tilts the northern latitudes toward the sun, the sun is highest in the sky-the summer solstice.  When the sun is lowest in the northern sky-the earth tilts away from the sun and gives us the winter solstice.

Since the summer solstice day time has exceeded night time. In theory the autumnal equinox is the point of equilibrium between light and dark, but at our latitude that day actually occurs on September 25th this year. This is, however, the day the Great Wheel celebrates and it does so because of the sun’s zero declination at earth’s celestial equator.

This week then the victory of the sun, made complete on the summer solstice, begins to wane. The dark god of deep winter gains greater and greater authority as the sun’s rays spread out over a larger area of earth, thus weakening them, and the number of hours that the sun is in our sky, even in its weakened condition relative to the soil, decrease steadily until the night of the winter solstice. Thus comes the fallow, cold time.

It is no accident that the harvest season is now. Over the 475 million years (give or take a hundred million) since plants made it out of the oceans and onto land, plants have adapted themselves to the conditions that work with their particular genetics. Key aspects of a plant’s life include carbon dioxide, soil nutrients, available fresh water, adequate sunlight and temperatures adequate for all these to work with the plant’s life cycle.

Thus, as the earth’s orbit carries it to different relationships with solar strength, temperatures change along with it.  At its maximum when the earth tilts toward the sun and the sun is highest in the sky, the sun’s rays fall on a smaller area of land. Here’s an excellent simulation. University of Nebraska-Lincoln.

Plants have had the past 475 million years to refine their growing season so that it takes maximum benefit of the sun’s strength. In a very real sense the growing season is a clock, or an astronomical observatory directly correlated to the earth’s orbit around the sun–The Great Wheel.

On a spiritual level, if we follow the ancient calendar of the plants, the season of external growth, flowering and seed making, is waning now. Just as the plant either dies out and anticipates its rejuvenation from scattered seed or goes dormant and waits with stored energy below ground in roots or corms or bulbs, so we might consider this season as the one where we shift inward, away from the external demands upon us and the expectations put on us there.

Now we shift toward the interior life, the Self becomes more of a focus, our spiritual life can deepen. We can see this shift in the human life cycle if we compare the second phase of life with its emphasis on family creation and nurture and career, to the third, with its pulling back from those external expectations. The third phase is a post growing season time of life, not in the sense that growth ends, but that its focus is more down and in rather than up and out. The third phase is the fallow time.  Michaelmas on the 29th of this month is known by followers of Rudolf Steiner as the springtime of the soul.

The third phase marks the beginning of the springtime of the soul for the individual.
