2 | Qal | Alluvium | Alluvium | Quaternary | Unconsolidated clay, sand, silt, pebbles, cobbles and boulders. Olive gray to medium dark gray, weathering moderate brown. Finer alluvium such as sand, silt and gravel underlies many of the lower gradient streams, while steeper streams are frequently floored by bedrock or locally derived sandstone cobbles and boulders. Valley floors are narrow in the steep terrain of resistant sandstones (Pottsville Formation) and coarse colluvium is transitional with alluvium. Floodplains develop sinuosity on the less resistant strata of the Allegheny Formation and Conemaugh Group. Total thickness ranges from a thin veneer to 15 feet (5 m). | 01-01 | DMU Unit 1 | Qal | 40 | 255,255,179 | None | MGS_FRIEN2025.1 | Alluvial sediment | High | DMU01
3 | Qc | Colluvium | Colluvium | Quaternary | Unconsolidated cobbles, boulders and large blocks of sandstone and conglomerate. Light olive gray to yellowish gray. Typically derived from massive Pottsville and Allegheny Formation sandstones that were transported by gravity, debris flow, and freeze-thaw processes.

Shale is medium gray to black, thinly bedded, fissile, typically found in contact with coal and clay layers, and capped by resistant sandstone layers. Two minable coals are mapped (from top): Upper Freeport (uf) and Upper Kittanning (uk). The Upper Freeport is the most persistent and commonly mined coal bed in the Youghiogheny basin. The base is mapped on the top of the Homewood Sandstone.

Siltstone and sandstone are thin- to medium-bedded, light olive gray, argillaceous, micaceous, and frequently cross bedded in multi-stacked sandstone layers that outcrop as small ridges on hillsides and bedrock steps in streams. Thin fossiliferous shales and limestones of the Reynolds Member occur near the base of the formation. The base of the formation is mapped in red and green shale above the Wymps Gap Member of the Greenbrier Formation. The only exposure is in the South Branch Bear Creek valley. Total thickness is 450 feet (150 m). | 05 | DMU Unit 1 | Mmc | 603 | 128,204,255 | None | MGS_FRIEN2025.1 | Sandstone and mudstone | High | DMU10
12 | Mg | Greenbrier Formation | Greenbrier Formation | Mississippian | Limestone, shale, siltstone and sandstone. Four members are recognized but not mapped (Brezinski, 1989). The basal Loyalhanna Member is a reddish gray to light gray, arenaceous limestone with large-scale cross bedding accentuated by weathering. It is 50 feet (13 m) thick. The overlying Deer Valley Member is a light olive gray, massive, crystalline limestone with white to pink calcite veins and slickensides. It weathers to moderate yellowish brown and thin siltstone beds occur every 4-6 inches (10-15 cm). It is 15 feet (5 m) thick. The Savage Dam Member overlies the Deer Valley Member and is mostly reddish gray, grayish green, thin-bedded siltstone and variegated shale with mudcracks and light gray to white fine-grained sandstone. Sandstone layers are pale yellowish brown to yellowish gray, thick to massive, cross bedded, and calcareous. The member is 75 feet (25 m) thick. The uppermost unit of the Greenbrier Formation is the Wymps Gap Member, which is light olive gray to medium dark gray, shaly to argillaceous limestone with abundant brachiopod, bryzoan, and crinoid fossils. Bedding is thin to massive, ripple laminated, and sometimes nodular. A distinct fetid odor emerges upon breakage of some units and white calcite slickensides are present. The Wymps Gap Member is 45 feet (14 m) thick. The base of the formation is mapped at the base of the Loyalhanna Member. This unit is found in small historic quarries above South Branch Bear Creek.

Sandstone is predominant in the upper portion of the formation and is light olive gray, thin- to medium-bedded, flaggy, and weathers moderate brown. Some layers are cross bedded with erosional bases and shale rip-up clasts. The base of the formation is a massive yellowish gray to very pale orange conglomerate with rounded clear to white quartz pebbles ranging from 0.3-2 inches (0.5-5 cm). Occasional white, friable beds are present. The base of the formation is mapped below this massive conglomerate, which forms ledges and conglomerate block fields.

9 | bedding | Formed, arranged, or deposited in layers or beds, or made up of or occurring in the form of beds; esp. said of a layered sedimentary rock, deposit, or formation. The term has also been applied to nonsedimentary material that exhibits depositional layering, such as the "bedded deposits" of volcanic tuff alternating with lava in the mantle of a stratovolcano. | AGI_2011 | GLID08
1 | certain | Identity of a feature can be determined using relevant observations and scientific judgment; therefore, one can be reasonably confident in the credibility of this interpretation. | FGDC-STD-013-2006 | GLID01
16 | coal | An outcrop or trace of a coal bed or stratum. | MGS_FRIEN2025.1 | GLID14

12 | neatline | Map Outline | MGS_FRIEN2025.1 | GLID11
2 | questionable | Identity of a feature cannot be determined using relevant observations and scientific judgment; therefore, one cannot be reasonably confident in the credibility of this interpretation. For example, IdentityConfidence = questionable is appropriate when a geologist reasons "I can see some kind of planar feature that separates map units in this outcrop, but I cannot be certain if it is a contact or a fault." | FGDC-STD-013-2006 | GLID02
