Road Log of Short Side Trip to Famous Collecting Locality
in Blue Hill Shale Member of Carlile Shale
0.0 Junction of Saline Valley Road and U.S. Highway 183. Proceed westward on county road.
0.1 Crossing Saline River.
0.5 Crossroad. Turn right (north).
0.7 Crossing Saline River onto flood plain.
0.9 Ascending onto low terrace. High alluvial terrace in middle ground to left (west) ascends northward and merges with relatively steeply sloping surface that is probably a flanking pediment.
1.3 Blue Hill, Codell, and Fort Hays exposed in bluff on left at 10 o'clock. Large slump block capped by Fort Hays at 10:30.
1.4 Descending to flood plain of small tributary of Saline River.
1.5 Abandoned farm house on right. STOP. Walk across pasture on left to cutbank in Blue Hill Shale Member of Carlile Shale. Turn around and retrace route to U.S. 183.
2.5 Crossroad, turn left (east).
3.0 Junction of county road and U.S. 183. Turn right (south).
91.2 Crossing flood plain of Saline River.
91.4 Crossing Saline River.
91.5-91.6 High-level terrace alluvium in roadcut.
91.8-92.0 Loessial soil in roadcut.
92.5 Blue Hill shale overlain by (ascending) alluvium (chalky limestone gravel), loess, and colluvium.
93.2-93.5 Upper part of Blue Hill, Codell, and lower part of Fort Hays in roadcuts on right. Note slumped rock.
93.8-93.9 Upper part of Blue Hill, Codell, and lower part of Fort Hays exposed in large roadcut on right. Normal fault near center of north part of cut has displaced Fort Hays downward (relatively) so limestone lies opposite Codell. Low area between north and south parts of cut is a small colluviated valley with Fort Hays slumped to north at south side of old valley. Note channel-like structure near south end of cut.
94.0 Codell-Fort Hays contact exposed in roadcut on right.
94.1-94.3 Fort Hays Limestone Member of Niobrara Chalk exposed in cut on right. Fort Hays colluvium visible at north end of cut. Note channel-like structure near south end of cut.
94.4-94.5 Fort Hays exposed in low roadcut. Ogallala Formation caps hill west of highway.
95.1 Crossroad.
95.2-95.5 Ogallala Formation exposed in low roadcuts.
95.7 Smoky Hill Chalk Member of Niobrara Chalk exposed in low roadcut on left.
95.9 Smoky Hill exposed in roadcut on left.
96.1-96.3 Smoky Hill exposed in roadside ditches. For next several miles highway crosses upland surface of High Plains.
