APPENDIX N:

POTENTIAL FOSSIL YIELD CLASSIFICATIONS (PFYC) FOR GEOLOGIC FORMATIONS INTERSECTING PROPOSED CORRIDORS UNDER THE PROPOSED ACTION BY STATE

Tables N-11 through N-11 of this appendix Table N-12, were given a PFYC Class 3 summarize the PFYC classes and general designation because they are of unknown fossil locations of geologic units intersecting the yield potential. Due to the variability in source proposed corridors under the Proposed Action material for these sediments, the actual as identified on state geologic maps (usually at determination of fossil yield potential would be the 1:500,000 scale). The PFYC classes made on the basis of more detailed information (1 through 5) are discussed in Section 3.4 (maps and literature) and field surveys during a and defined in Table 3.4-2. For this analysis, project-specific assessment. all Quaternary sediments, summarized in
