Index No: NBM053900; Collected By: ; Sample Type: hand sample (missing); Notes: Rock chip/composite sample of "ferricrete," iron-oxide-cemented colluvium or talus of angular blocks and small fragments. Rock is locally gossanous and more or less solid hematite and limonite with vague bedding where clasts are present. Sample includes pieces from lower, middle, and upper parts. Base is indistinct-underlain by iron-oxide cemented blocks and bedrock(?) Ferricrete is approximately 2-3m thick, dips approximately 03� W, crops out over only a small area in canyon bottom. Shallow shaft with remains of windlass and 75-foot trench approximately 1m deep have explored this. It looks like a chemical precipitate, not sedimentary. Weiss 11/11/95
