South wall of Little Tahoma Peak, about 400 feet below its summit. Mudflow breccias enclosing streaks, lenses, and tongues of partly brecciated lava. Such mixed accumulations of lava and breccia probably formed from thin lava streams that were shattered by steam explosions as they glided down steep slopes and mixed with mud, slushy snow and melt water. The dips are primary and are as much as 30 degrees. The cliff is about 100 feet high. Mount Rainier National Park, Washington. ca. 1959. Figure 51, U.S. Geological Survey Professional paper 444.

Lower part of the basal ash flow in the Stevens Ridge Formation on Backbone Ridge. The light-colored ash flow churned through soft saprolite on the pre-Stevens Ridge land surface and included fragments of the saprolite and less-weathered Ohanapecosh rocks in the lower 8 feet of the deposit. Mount Rainier National Park, Washington. ca. 1959. Figure 22, U.S. Geological Survey Professional paper 444.

A plug of flow-banded rhyolite in the Sarvent lava complex of South Cowlitz Chimney. The south (right) side of the plug flares outward, truncating and overriding nearly horizontal bedded rocks of the Ohanapecosh Formation. The plug's sheer rock face is about 500 feet high. Mount Rainier National Park, Washington. ca. 1959. Figure 17, U.S. Geological Survey Professional paper 444.

Interbedded volcanic sandstone and siltstone (dark) of the Ohanapecosh Formation, viewed from the east side of Backbone Ridge. Note the prominent ripple marks in the upper half of the photograph, the load casts of sandstone bulging downward into siltstone (upper center and at the base of the stratum partly obscured by a dark stain), and abundant flattened pumice lapilli in the sandstone bed extending across the center. Mount Rainier National Park, Washington. ca. 1959. Figure 16, U.S. Geological Survey Professional paper 444.

Megascopic features of Ohanapecosh metamorphism. Sperical concentrations of laumontite in pumiceous tuff-breccia on the east side of Backbone Ridge. Note the friability of the rock. Mount Rainier National Park, Washington. ca. 1959. Figure 28, U.S. Geological Survey Professional paper 444.
