"NTS 87-H/4 is underlain by the middle to upper Kilian, Kuujjua and Natkusiak formations of the Neoproterozoic Shaler Supergroup. Together with at least 5 diabase sills (type 2), spaced at regular intervals within the host sedimentary rocks, the strata comprise the gently south-dipping northern limb of the Holman Island Syncline. The northern half of the map area is dominated by a thick sill, which forms a prominent southeast dip slope down to the Kuujjua River. Sedimentary strata are best exposed along a prominent cuesta that faces north-northwest along the south side of the Kuujjua River. The upper two members of the Kilian Formation are sporadically exposed along the base of the cuesta. Crossbedded quartzarenite of the disconformably overlying Kuujjua Formation is prominent along the cuesta's face along with conformably capping basalt flows of the Natkusiak Formation. Both are also well exposed along the flanks of two, north-flowing tributaries of the Kuujjua River. Several steep, northwest-striking, west-side down normal faults are spaced evenly across the map area"--Abstract.
