Location and accuracy This occurrence, called the Cleveland Creek gossan by Herreid (1970), is at an elevation of about 600 feet on the south side of hill 738 in the headwaters of Cleveland Creek, an east tributary to Cripple River. The occurrence was mapped by Bundtzen and others (1994). It is 2,400 feet northeast of the Nome-Teller road; the location is accurate.

Geologic setting

Geologic description

An iron oxide occurrence lies on the south side of hill 738 in the headwaters of Cleveland Creek in or adjacent to the massive marble unit of Bundtzen and others (1994) Herreid (1970, p. 18) called this the Cleveland Creek gossan and found anomalous amounts of lead and zinc, as at the nearby Cub Bear prospect (NM133) and some other iron oxide prospects of the Sinuk River area. The Cleveland Creek occurrence may be in a structural and stratigraphic setting similar to those at the Quarry (NM135) and Galena (NM130) prospects.
