Lower Colville River, Locality 86/37
|Northern Alaska Map|
Kogosukruk Tongue of the Prince Creek Formation. At the base of the exposed section is a cross bedded bentonitic siltstone underlying a brown seat earth beneath a thin (5 cm) coal overlain by a paper shale (2.5 cm) and a bituminous coal (7.5 cm thick). Above this is a brown uncosolidated mudstone (approximately 20 cm thick) that coarsens upwards to a more indurated sandy mudstone, again approximately 20 cm thick, containing abundant wood fragments.
