Amalgamated conglomerate, largely cobbles, some boulders and pebbles, clast supported, coarse sandy matrix, interbedded sandstone lenses, feldspathic to volcanofeldspathic, cobbles largely intermediate plutonics, some gabbro and rare granite clasts, sands weakly cemented to friable. Section considered typical of the thousands of feet of conglomerate exposed in the Naknek Formation near Ugashik Lakes. Interpreted as braided stream deposits on steep, wet alluvial fan, coarse material suggests proximity to active scarp of Bruin Bay fault. Sandstone, olive gray, pebbly to conglomeratic, well rounded clasts, discrete pebble trains in lower 1/2, grades up to clast supported conglomerate in upper 1/2. Imbrications: 186, 173,210, 160. Thick-bedded, amalgamated conglomerate beds with occasional 1/2-1 1/2 foot thick lenticular sandstone interbeds, interpreted as braided stream deposits on a steep alluvial fan. 82/151 . - rl,) VI) VI) VI) VI) VI) VI) VI) UI) VI) UI) VOUI)UI) VI) Ul)o.A ~ ,., "\ 'Î, 1'\'" 'Î, 1'\ 1\ f'o f'o f'o 1'\ "\ t'I f\ (" ~I,) o~; (1)001)001)000001)°1) 00 o~ 01) (1)01)0, I,)<Q-I)-Q-O¢QOQOQOQ0I)0Q0I)0QOQOOOQO\. 000000000000000000000 ~OoQQ~OUOQOI)OQOQOQOI)QI)OQOI)QQQQOOQ I,)%%~%%%%Q.I)%~~~~~I)%Q 0QQQOQ0I)0QOQOQOQ0I)0I..~OQ0l)o, t,)~Q~I)~O~I)~t,)~I)~I)~I)~Q~I)~I)~Q~Q~I)~I)" """00 'wi 00000 'wi 00 Vo ""00 'wI,_ v_v.
