A small iron mine near the head of Negro Creek.
Sec 7,8 T22N R17E
Geodes
Tectonics: Iron-Nickel-Chromium deposits (residuum of weathering products) overlie serpentinized ultramafic rocks (Broughton, 1943, p. 9-13) of the Ingalls Complex, a Jurassic ophiolite complex (Miller, 1985, p. 27; Tabor and others, 1982, p. 5-6)
Deposit: Deposit consists of reworked residuum derived from underlying ophiolite complex and Swauk Formation
Deposit type: Lateritic Ni
Geology: Ingalls Complex is an accreted ophiolite terrane Some of the laterites were reworked prior to deposition of the Eocen Swauk Formation. Lamey (1950, p.) tentatively
