The pointedly uncluttered installation featured eight works (all 2012) in video, sculpture, drawing, and sound, as well as a bit of sly architectural intervention, and it contained certain individual moments of interest: Untitled (Dog), a faithfully rendered Great Dane inflated to humorously Brobdingnagian proportions; Untitled (Sun), a modified geochron
in which all political borders and points have been erased, leaving the day to pass its transit across a great undifferentiated terrestrial mass; an untitled, easily overlooked cut made into one of the gallery walls whose bottom edge was incongruously finished with a pale marble ledge.
Kemp's (2008) results included 11 stable isotope analyses on jackrabbit collagen by Geochron Labs in Cambridge.
If the 11 samples processed by Geochron that lack C:N ratios (Kemp 2008) are included, jackrabbits comprise roughly 85% of the samples analyzed from 41MM340.
The analysis was performed by Geochron

This is part of the Blake River assemblage confirmed by recent geochron
dates released by the OGS (Ontario Geological Survey) in September 2005.
One way to explain the age discrepancy between LSCE and Geochron
is to assume that the charcoal dated in the USA originated in a 15 000-year-old tree whereas the charcoal dated in France had its origins in a tree felled more than 15 000 years earlier.
