Prologue Land



I've always liked books about places and how the environment has changed over time: ecological histories, tales of peoples' places, studies of adaptation or calamity. Reading one lately--that I won't single out because it's no more culpable than most--reminded me of a fault in the genre. And by fault, I mean giant hole, chasmic abyss, gaping lacksomeness, over which authors sometimes stretch a canvas whose tableau fools only those who are not paying attention. This gap began opening soon after large numbers of humans began writing, and goes by the name Prehistory.


Literacy begat History, which captured some of what came before and more than you can read ever since, but which also is nearly blind to all but the most exalted knowledge more than a few decades before its arrival. Eventually, Natural History felt pent up and begat Geology, and now we can read stacks of books not just about the earth and how it got that way, but also about the history of life on earth (Paleontology, Son of Geology). 


That span between the arrival of human hordes capable of altering entire ecosystems and their bothering to write about it remains mostly unknown even to scholars in the field. In places like Hawai'i Island, we are lucky because Kamakau, Malo, Kalokuokamaile, and others recorded the agricultural history and knowledge of their people. But mostly the sources for historians of the land are a few explorer accounts, the occasional missionary (Christian or Capitalist) excoriation of native practices, and metaphorical allusions coded into "mythology" collected by anthropologists long ago. To the modern outsider, the non-descendants who write about such things, the prehistoric past becomes nothing more than prologue, something influential but not not the subject of the book. An acknowledgment, without so much knowledge.


In some cases, there are those who know what came before. Archaeologists have coaxed information from pollen, charcoal, and residues in clay pots; they've documented ancient landscape features that once were gardens and fields. Native people did not all go to the city and forget, and some of them know the songs and stories that told their ancestors how to take care of the land and be cared for by it. Native or not, aware or not, some people carry on ancient relationships to the land and ways of gathering from it, tending to places, or growing food that make no explicit link to the past, dumb traditions imparting wisdom.


Aside from some of the archaeology, most of this never even makes it into the prologue. Instead, we get the same modern myths. That Indians lived in a pristine wilderness, or planted corn with a fish in every hill. Maybe the author recognizes that native people managed the landscape, maybe even gives it a real chapter, but tells what was happening at the moment Europeans arrived as if this explains the preceding fourteen millenia. Admire the snapshot and move on.


Shrinking the wisdom of 600 generations into a vignette, a counterpoint to a tale of destruction, even a wistful memory, is a loss. For the cultures that learned lands and loved them as family, it is the sadness of ways gone away. For those of us now, it is loss of a future. What worked for grandparents of grandparents can work for our grand-kids who also will not have abundant oil and chemicals, who may endure drastic climate change. We in the prologue to the future would do well to do more to learn about the ecological history of prehistory.

Bifurcation. No, It A Crew Fib.

Ah, homophony and loose spelling, you make palindromic(ish) titles possible.



But you cannot make them make sense. I do wanna talk about bifurcations, though. There's one in the photo above, which is in hills above the Columbia River at a couple thousand feet elevation, roughly. Fortuitous snowfall and gratuitous editing render this bifurcation as a Y on the hillside, a game trail splitting. The top one goes higher, and the other goes...


I don't really know where it goes. It passes an outcrop right about where hillside and horizon cross paths, and sometimes outcrops expose chert, which was useful for tools. But it probably heads into the draw, closer to cover and water. 


Anyway, the paths part ways. Archaeologists like myself and others who look at how humans and other animals use the land pay special attention to bifurcations in trails. Why does it split here? Do the two forks head to very different resources or destinations, does the point of separation show any signs of being a site, a spring, something else that would draw in beasties and bipeds? 


The forkal focal point is also a pivot. A bifurcation, viewed from the other direction, is a convergence. In the photo, two trails merge to one, headed to the Columbia. Heading up, the trails appear dendritic, branching to deer hide-outs and springs, root grounds and rock sources. Going down, they flow like tributaries, rivulets meeting to form creeks, streams, and rivers dumping into the big river at a village or fishing place. In the root season, trails headed out in various directions, allowing women to disperse to the many places they could dig. When the fish ran, the men could converge at the falls and pools where they were most easily plucked from the flow. 


Backing way off, getting the eagle's view, "bifurcation" looks too simple, and not just because of the palindromic perspective shifts. The parted ways may meet again. The paths up from the river do not simply branch and branch again. There are intersections, three and four-way splits, convergences and divergences of human and game routes. The bi- and trifurcations, once you are removed from their tangle, look more like nodes in a web, neurons in the collective animal brain. Each a dumb switch, maybe, but together a brilliant chaotic topology. The binary split/merge options of the trail-bound perspective become something more.


So, having branched off from my original tidy premise, I sputter to a halt. Trails do that sometimes.
