Summary:
Named for Pagoda Mountain, southern Flathead Co, MT, Montana folded belt province. Type locality is on eastern side of peak, N 20 degrees E of top of Pagoda Mountain, in SW1/4 sec 3, T22N, R13W. Unit occurs in area of Lewis and Clark, Flathead, and Swan Ranges, in southeastern Flathead, northern Powell, and northwestern Lewis and Clark Cos. Thickness varies from 400 ft in Dearborn River area to 87 ft in Wall Creek area. Is 168 ft thick at type locality, where it consists of a lower 75 ft of thin-bedded, cream-gray, platy, oolitic limestone which weathers white-gray; a middle 30-ft zone of thin- to medium-bedded, fine-grained chocolate-colored limestone with minor flaky, buff clay throughout; and an upper 56 ft of cream- to chocolate-gray, thick-bedded, massive oolitic limestone. Limestones of Pagoda vary greatly in area, ranging from light-gray to tan and chocolate-colored, and varying from black, fissile shales to red and green limestone-conglomerate in Pentagon Mountain area. Conformably overlies Steamboat limestone (new); conformably underlies Pentagon shale (new). Eight measured sections. Correlation chart. Middle Cambrian age, based on stratigraphic position. [Author uses rank terms oolite and formation interchangeably.]

Summary:
Redescribed from Pagoda oolite to Pagoda limestone in Lewis and Clark Range area in Flathead, Powell, and Lewis and Clark Cos, MT in Montana folded belt province. Type locality changed to Prairie Reef area in NE1/4 sec 9, T21N, R11W, northwestern Lewis and Clark Co, MT. Unit is primary limestone, commonly oolitic, with minor shale. Pagoda overlies Dearborn limestone as rocks formerly assigned to Steamboat limestone are included in Dearborn. Pagoda underlies Pentagon shale. Tentatively correlates with lower part of Bloomington limestone in Blacksmith Fork area, UT, Swasey limestone in House Range, UT, and in part with upper part of Highland Peak limestone, Highland Range, NV. Measured sections. Correlation chart. Cross section. Middle Cambrian (Albertan) age.

Summary:
Tentatively extends unit into area of Arsenic Peak in Sawtooth Range, southwestern Teton Co, MT, Sweetgrass arch. Only upper part of Pagoda is exposed. Possibility exists these rocks may belong to Pentagon shale, though lithology is different than Pentagon occurring to west in Silvertip quad. Here, Pagoda underlies Steamboat limestone rather than Pentagon shale. Underlying rocks not exposed. Stratigraphic chart. Middle Cambrian age.

Summary:
Divided into shale (lower) and limestone (upper) members. Both members well exposed at Nineteen Mountain, Prairie Reef and Slategoat Mountain in western part of map area, Lewis and Clark Co, MT, Montana folded belt province. Thickness ranges from 250-360 ft in Pretty Prairie quad (GQ-454, Mudge, 1966); averages about 350 ft thick in Glenn Creek quad (GQ-499, Mudge, 1966). Upper limestone member exposed on west side of north end of Big George Gulch in Arsenic Peak quad (GQ-597, Mudge, 1967) in Teton Co, MT, Sweetgrass arch. Here thickness is 275 ft. Conformably overlies Dearborn Limestone with distinct contact; conformably underlies Steamboat Limestone. Correlates in part with Wolsey Shale and Meagher Limestone in south-central MT. Geologic map, stratigraphic chart. Middle Cambrian age.
