Location and accuracy The approximate location of this unverified occurrence is in the south part of Section 31 at an elevation of about 4250 feet, on an east-facing mountainside overlooking the toe of Gracey Creek Glacier (Koch, 1997, p. 53, loc. 81). The location probably is accurate within about a quarter of a mile.

Geologic setting

Geologic description

The country rocks in the area of this reported occurrence are Tertiary or Cretaceous leucocratic quartz monzonite and granodiorite of the Coast Range Batholith, and roof pendants of Mesozoic or Paleozoic metapelitic and metavolcanic strata, locally including marble (Koch, 1996). On Koch's (1997) map, the occurrence appears to be in the plutonic rocks between metamorphic roof pendants, or alternatively, in an outcrop of metamorphic rocks too small to show at the scale of Koch's map. Other than location and unverified occurrence of silver, no other geologic information about this site has been made public.

Additional comments

Koch's scanty description of this occurrence in his (1997) report may have been taken from a U.S. Bureau of Mines claim map, but there is no reference to one in his report.
Site is in Misty Fiords National Monument.
