Fig. 22 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. 22. Schematic diagram showing the hypothetical development (A–F) of an early Miocene halfgraben or graben system in the vicinity of and south of Kimberly post office, John Day valley, Oregon. Abbreviations: k, Kimberly Member; jc, Johnson Canyon Member; rc, Rose Creek Member; twb, Twickenham Basalt; DCGF, Dead Cow Gulch fault; RCF, Rose Creek fault.

Fig. 12 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. 12. Debris flows characterize Rose Creek Member outcrops along the east wall of the John Day valley south of Kimberly, at Sutton Mountain, and at Balm Creek. Rounded clasts of welded tuff derived from the Picture Gorge ignimbrite, vitric tuff from subjacent John Day units, and clasts of Deep Creek tuff, are supported in a finegrained tuffaceous matrix. Masses of watersaturated volcanic ash moved downslope into stream courses where fluvial gravels were incorporated and deposited as local debris lenses.
Fig. 11 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. 11. The Rose Creek Member at the early Hemingfordian mammal locality Picture Gorge 36. Coarse polymictic gravels, sands, and overlying tuffaceous sediments of the Rose Creek Member (rc) incise the Kimberly Member gray tuffs (k). Dashed white line marks the contact between the two units.
Fig. 18 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. 18. The Great Plains oreodont Merycochoerus from the Childs Frick collection of the American Museum of Natural History provides biochronologic control for the occurrence of this indicator taxon in the upper John Day Formation, Oregon. Because many upper John Day taxa are represented by few individuals, the larger Frick samples of Arikareean/Hemingfordian mammals are critical to accurate age assessment. The graph measures the progressive fusion and posterior extension of the premaxillae in time, most likely related to ongoing development of a tapirlike proboscis in this large oreodont. The triangle labelled ''Rose Creek'' refers to UCMP 76848 from Picture Gorge 36.
Fig. 17 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. 17. Uppermost rock units of the John Day Formation at Sutton Mountain, Wheeler Co., Oregon. These exposures along the southern face of Sutton Mountain demonstrate the superposition of the Rose Creek Member on the Johnson Canyon Member (''Unit D'') in the N½, sec. 33, T10S, R21E, Sutton Mountain 7.5 min. quadrangle, in an area where Hay (1963: figs. 2, 4, section 11) also measured one of his thickest sections of upper John Day rocks.
Fig. 19 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. 19. Structural trends south of the Blue Mountains in the eastern subregion along the course of the John Day River (modified from Fisher, 1967). Upper John Day rocks east of Spray in Haystack Valley (Haystack Valley Member [revised] and Balm Creek Member) west of the Richmond fault differ from upper John Day rocks east of the fault in the vicinity of Kimberly (Johnson Canyon Member superposed on Kimberly Member). In both areas and at Sutton Mountain, however, the Rose Creek Member unconformably overlies and incises all of these upper John Day units and is the terminal member of the John Day Formation in the region.
