A Cu occurrence/claim located 4.9 km (3.1 miles) SSE of Hoskinnini Mesa, on the SE edge of the mesa. Lies in what was termed the Crescent channel by the former US Atomic Energy Commission, and Channel No. 28 by the USGS. NOTE: This locality is not listed in the USGS MRDS database.
Mineralization is a paleochannel that trends N45W and is 150 feet wide and 50 feet deep of medium-grained, cross-bedded sandstone.
The channels (includes channel 27) crop out on the southeast edge of Hoskinnini Mesa, and are easily accessible from a graded dirt road on the mesa top. The road extends west from Navajo Indian Reservation Route 1 (Kayenta-Mexican Hat road), follows Adahchijiyahi Canyon to Todicheenie bench, crosses Todicheenie and adjacent uplands and finally ascends Hoskinnini Mesa.
Exposed consolidated sedimentary strata range from the Organ Rock tongue of the Cutler formation, along the base of Hoskinnini Mesa, to the Shinarump member of the Chinle formation, and form the mesa cap. The Shinarump member, which overlies the Moenkopi formation, form; a vertical cliff about 50 feet high, and is veneered by dune sand which ranges in thickness from a thin film to a cover more than 20 feet thick.
These strata form the asymmetrical Organ Rock anticline with its gently dipping west flank and steeply dipping east flank. The two channels crop out near the crest of the structure.
Channel 28 (Crescent) strikes about N. 45° W., is about 150 feet wide, and has been cut about 50 feet into the Moenkopi formation. Channel strata consist predominantly of light-gray crossbedded medium-grained sandstone with local lenses of conglomerate near the base of the channel. Blue and green secondary copper minerals (malachite and azurite) are scattered widely in the basal rocks, and limonite stains the outcrop and the joints. Radioactivity (0.05 milliroentgen per hour) is only slightly above background (0.03 milliroentgen per hour).
