Crossbedded sandstone in upper part of lower Nanushuk Formation on Slope Mountain, Philip Smith Mountains quadrangle

Figure 11. Crossbedded sandstone in upper part of lower Nanushuk Formation on Slope Mountain, Philip Smith Mountains quadrangle. Predominance of planar crossbedding and local occurrence of herringbone crossbedding (above arrowhead) suggest deposition in a shoreface system influenced by tidal currents (perhaps a tidal inlet on a barred coast). View to north. Photograph by D.W. Houseknecht.
