TUFA

Tufas, like mineral flowers, emerge, protrude, and fragment as a lake recedes.  Bud, blossom, seed, left high and dry.  Tufas congeal in crenate patterns, constellated, crystallized, caverned, calcified froth. 

This tufa boulder formed under the waters of a bay of Pleistocene Lake Lahontan in northwest Nevada.  An immersed spring emits dissolved calcium which combines with carbon in the lake water to form calcium carbonate into a sort of crystalline structure, which is then eroded. These deeply carved petroglyphs, vulva-like shapes and linear incisings, are undated.

The petroglyphs on this boulder appear as emblems of desire, as invocations, perhaps entreating sexual fecundity, necessary replenishment. In these landscapes as marvelous, saturated dream-space, I am reminded of Max Ernst’s frottages and textured paintings.  

The boulders' location is proximate to the justly famous, oldest dated petroglyphs in North America, also carved on tufa. Those dated petroglyphs look to the east over Winnemucca Dry Lake, east of Pyramid Lake - both remnant lakes of pluvial Lake Lahontan. The Winnemucca petroglyphs were determined by Larry Benson and associates in 2013 to date to at least 10,500 years ago.

 

Another carved tufa boulder near the spring.

A very hot spring, once at the bottom of a pluvial (Pleistocene) lake, located on the playa near the tufa boulders.

CODA
We all belong not just to our present moment, nor to the place in which we find ourselves at that moment, but to a far greater system of changes which have occurred throughout Earth's history and will continue to occur long into the future. The present convulsions of the planet are the result of the whole Earth system trying, in response to terrible pressures, to shift itself, often violently, into a new set of alignments, and we are part of those changes. We are the weather, and the water; we are the lionfish, too, changing our environment as we are changed by it. This realization can be humbling. and it can be hopeful too. We belong to the whole timescale of history. —James Bridle, from Here Come The Lionfish,  Emergence Magazine, Vol. 5: Time (2024)

MATRIX

The sea, turned to stone, is laughing
a last laugh made of waves.
— Federico García Lorca

In the beginning all was Molten. Caressing, congealing Creation arrives. Stone appears, birthing Earth. Restless Movement brings Life to all things. Beings wake, blink, consent. Carrying stone, placing stone, carving rock in the Telling time of prayer. The carving of the petroglyph, a fleeting phase in the life of the stone. Yes, the stone, alive. Actor and witness. Change, the constant forgiving. In the faraway end… all is Molten.

CODA
Is life immortal? Don't ask life,
for it doesn't even know what life is.
We are the ones who know
that one day it too must die and return
to the beginning, the inertia of the origin.
The end of yesterday, today, and tomorrow,
the dissipation of time
and of nothing, its opposite.
Then will there be a then?
will the primigenius spark
light the matrix of the worlds,
a perpetual re-beginning of a senseless whirling?
No one answers, no one knows.
We only know that to live is to live for.

    — Octavio Paz (Mexican 1914-1998)
