Art engenders becomings, not imaginative becomings - the elaboration of images and narratives in which a subject might recognize itself, not self-representations, narratives, confessions, testimonies of what is and has been - but material becomings, in which these imponderable universal forces touch and become enveloped in life, in which life folds over itself to embrace its contact with materiality, in which each exchanges some elements or particles with the other to become more and other.

Grimes Point Archaeological Area, an extensive, fully accessible, and signed field of dark boulders with archaic petroglyphs, is adjacent to Highway 50 east of Fallon.
The locale looks west and south over the Carson Sink, a terminus of the Carson River, in Churchill County, Nevada. Well-managed by the BLM, it is listed on the National Register of Historic Places.
Some boulders bear arrays of deeply patinaed cupules. These ancient “conical pits” associated occasionally with lines or grooves led to Baumhoff and Heizer’s in 1958 (and 1962) typing the “pit-and-groove” petroglyph style. They conjectured that this style represented the earliest petroglyphs in a wide expanse of the Great Basin. Though they cautioned their proposal as tentative pending dating, many rock art writers in the ensuing decades reified this style as fixed truth. I do believe these cupuled boulders are, in many of the instances I’ve seen in the northern Great Basin and Columbia Plateau, early Holocene (7,000+ years before present time [BP]). However, the designs and configurations are not rightly constrained as fixed cultural “elements,” while solid dating remains elusive. A worldview beyond grasp. What we have is the beauty of the densely-colored, dimpled desert boulders recalling watery eras – a sensible materiality.
