A granite pestle and an associated soil control sample recovered from Feature 2, an exposed, low-lying granite bedrock milling station at Site CA-TUO-4818 in Yosemite National Park, California, were submitted for protein and organic residue analysis. The pestle was tested for organic residues using Fourier Transform Infrared Spectroscopy (FTIR), and for protein residue using cross-over immunoelectrophoresis (CIEP).
