Fig. 8 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)
Fig. 8. Section HS1, situated 0.5 mi (0.8 km) east of the Beardog Section, occupies the southern margin of the south limb of the Balm Creek syncline. Here steeply dipping strata of the south limb become horizontal and abut directly against the Richmond Fault of Fisher. The section from 2360 to 2660 ft (Units 2A, 2B) represents the Haystack Valley Member (revised), which is fossilferous except for Unit 2B. Unit 2B (2630–2660 ft) includes a fluvial channel complex at the base overlain by the GMAT marker bed; GMAT correlates Section HS1 with measured sections of figures 4 and 5. The

Fig. 3. Stratigraphic nomenclature applied in previous studies to Oligocene and early Miocene rocks of the John Day Formation in the eastern subregion. The ignimbrite of Hay (1963) occurs within the Turtle Cove Member of Fisher and Rensberger (1972), who recognized its importance as a regional marker unit within the John Day Formation.

Fig. 10 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)

The contact (c) between the lower and upper units of the member separates tuffaceous sediments with calcareous paleosols in the lower unit from tuffs overprinted by siliceous paleosols in the upper unit. Monomictic vitric tuffpebble conglomerates (m) are restricted to the lower unit. PG, Picture Gorge Basalt Subgroup.
Fig. 2 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)
Fig. 2. Map of the John Day River valley with geographic localities discussed in this report. Our field study of upper John Day rocks was focused in the Haystack CreekBalm Creek area in Haystack Valley east of the town of Spray; in the vicinity of Kimberly post office and for ~20 mi to the south of Kimberly along the John Day valley; and at Sutton Mountain east of Bridge Creek. The geographic area within the circle includes the classic John Day exposures studied by Merriam (1901), Hay (1963), and Fisher and Rensberger (1972).
Fig. 6 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)
Fig. 6. Uppermost part of the Beardog Section: a basal fluvial channel of the Rose Creek Member is incised ~50 ft into the Balm Creek Member. Debris flow and finely laminated lacustrine tuffs comprise much of the channel fill overprinted by numerous siliceous paleosols. The Rose Creek Member was not identified by Fisher and Rensberger (1972: section 10) whose measured section terminated below this stratigraphic level.

Fig. 21. Schematic crosssection of the John Day basin from Middle Mountain to ~3 mi south of the Blue Mountains uplift (based on Fisher, 1967: fig. 5). Note the thick upper John Day strata (i.e., above Tji) near the center of the transect in the vicinity of Kimberly (Kimberly, Johnson Canyon, and Rose Creek Members), and to the north of the Richmond fault in the Balm Creek syncline (Haystack Valley Member [revised], Balm Creek and Rose Creek Members). Length of crosssection: ~25 mi (~40 km). Abbreviations: Tj, John Day Formation; Tji, Picture Gorge ignimbrite; Tc, Clarno Formation; pT, preTertiary rocks; PGBS, Picture Gorge Basalt Subgroup.
Fig. 14 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)
Fig. 14. West wall of the John Day valley south of Kimberly at Dead Cow Gulch. The Rose Creek Member (a) caps the Dead Cow Gulch measured section (fig. 13) south of the Dead Cow Gulch fault (c); the V6668 section (b) occurs north of the fault. The fault follows a westtoeast trend along the gulch; flows of the Picture Gorge Basalt (d) abut the fault plane.

Fig. 1 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)
Fig. 1. The principal exposures of the John Day Formation of northcentral Oregon occur along the course of the John Day River (eastern facies), Crooked River (southern facies), and Deschutes River (western facies). The eastern and southern facies have produced abundant fossil mammals that form the basis for an Oligocene and early Miocene mammalian biochronology in the Pacific Northwest. This report examines the upper John Day Formation of the eastern facies, outcropping along the John Day River, geographically situated between the Blue Mountain anticlinal uplift and the OchocoAldrich Mountains axis.
Fig. 10 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)
Fig. 10. Stratigraphic profile of the east wall of the John Day valley south of Kimberly from Rose Creek south to McCarty Creek (Foree South). The Rose Creek Member rests with angular unconformity on older John Day rocks (Turtle Cove and Kimberly Members). The early Hemingfordian mammal fauna from the Rose Creek Member comes primarily from Picture Gorge 36 and sites at Rose Creek.
Fig. 23 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)
Fig. 23. Stratigraphic nomenclature applied to the upper John Day Formation in the Balm Creek syncline east of Haystack Valley: a, Fisher and Rensberger's section 10 (equates to the Asher Section of this report); b, upper John Day strata of the Balm Creek syncline as interpreted in this study. 1 Later assigned by Rensberger (1983) to the Haystack Valley Member.
Fig. 4 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)
Fig. 4. Stratigraphic profile of the upper John Day Formation from the mouth of Haystack Creek 1 mi (1.65 km) eastward to the Balm Creek drainage. Four measured sections are correlated using a gray massive airfall tuff (GMAT) and local monomictic weldedtuff conglomerate bodies (see p. 17 for lithologic key). Rocks below the GMAT marker bed are particularly fossiliferous and are the source of the mammal fauna from the Haystack Valley Member (revised). Entoptychine rodents occur no higher in the revised member than the 40–50ft level of the Asher Section (lower part). Unit thicknesses in lowermost 160 ft are estimated within ±5%.
Fig. 9 in Geology And Paleontology Of The Upper John Day Beds, John River Valley, Oregon: Lithostratigraphic And Biochronologic Revision In The Haystack Valley And Kimberly Areas (Kimberly And Mt. Misery Quadrangles)
Fig. 9. Stratigraphic profile of the east wall of the John Day valley south of Kimberly from Spring Creek to Rose Creek. Downfaulting of the Rose Creek Member along the Rose Creek fault and at faults in the vicinity of Spring Creek results in offset of>300 ft (from ~2735 to ~2400 ft) over a distance of 1 mi (1.6 km). The profile continues to the south in figure 10.
