The Nation Peak occurrence is located within the Gladys Lake Ecological Reserve within the Spatsizi Plateau Wilderness Park, approximately 2.5 kilometres southeast of Nation Peak and 6.5 kilometres southwest of Cold Fish Lake, about 68 kilometres southeast of the village of Iskut. The showing lies within the precipitous terrain of the Skeena Ranges.

The showing was briefly reported in J.W. McCammon's list of barite occurrences (ca. 1958) and evidently has not been explored (Industrial Mineral File - List of Barite occurrences). Barite has been reported with galena in small veins.

The regional geology comprises Stikine Terrane Permian to Jurassic eugeosynclinal rocks and Upper Jurassic to Cretaceous clastic sediments deposited in the Bowser Basin. Middle Jurassic and older rocks have been intruded by granitic to dioritic bodies belonging predominantly to the Late Triassic to Late Jurassic Hotailuh batholith. Within the Bowser Basin, regional scale faults and folds have a northwest trend in response to a northeast-southwest contraction.

Regional mapping by the Geological Survey of Canada (Open File 1005; 1080) indicates that locally, Upper Triassic Stuhini Group and unnamed Upper Triassic to Lower Jurassic rocks form an inlier within the Bowser Basin. Units are described as andesitic to rhyodacitic flows, breccia, and tuffs of aphyric to porphyritic texture and fine to coarse clastic and carbonate sediments. More recent geological information indicates that the inlier is Lower-Middle Jurassic Spatsizi Group undivided sedimentary rocks and bimodal volcanic rocks of the Lower Jurassic Cold Fish Volcanics of the Hazelton Group.
