Album caption: History and Dynamics of Glaciation in the Northern Yellowstone National Park. Aerial photograph showing glacial features on the west side of the Gallatin Range. Ice flowing through passes along the Gallatin Range divide (open arrows) combined with glaciers from local cirques (at lower right) to form a glacier in the Gallatin valley large enough to spill northward and block Fan Creek. The main stem of the glacier moved down the Gallatin valley to the trench following U.S. Highway 191, whereupon one lobe flowed downstream (north) and another moved south into the drainage of Grayling Creek. ...

Album caption: History and Dynamics of Glaciation in the Northern Yellowstone National Park. Convergence of ice streams toward Gardiner to form the northern Yellowstone outlet glacier. 1, Drumloid topography in Gardners Hole (also frontispiece) and adjacent areas formed by northeasterly to northerly flow from the Gallatin Range icecap and the plateau icecap between the Gallatin and Washburn Ranges. 2, Northerly flow between Obsidian and Lava Creeks left striations and basalt erratics on Bunsen Peak. 3, Striations and scour features cross the crest of the northwestern part of the Washburn Range. 4, Glacial-scour features on Mount Everts and adjacent uplands indicates flow swinging from westerly to northwesterly....

Album caption: History and Dynamics of Glaciation in the Northern Yellowstone National Park. Glaciation of Yellowstone National Park was more extensive and involved more interaction of ice from multiple sources than previously recognized. The drumloid topography (arrows) was formed by ice about 600 m thick flowing oblique to the Gallatin Range front; it shows that glacial flow from the valleys in the Gallatin Range was diverted northward by a thick icecap on the plateau east of the range. Thus, the northern Yellowstone glaciation must be considered in terms of coalescing icecaps that covered almost the entire landscape rather than just as valley and piedmont glaciers emanating from the main ranges.

Album caption: History and Dynamics of Glaciation in the Northern Yellowstone National Park. Aerial view of glacial souring, streaming and molding features produced by ice from the Beartooth uplift as it flowed southward into the Yellowstone Valley. Note strong convergence of flow with other ice coming down the Lamar-Yellowstone drainage. Photograh by NASA, 1969. Wyoming, ca. 1968. No index card. Published as Figure 30 in U.S. Geological Survey. Professional Paper 729-F. 1979.
