-fabulous section exposing the transition from cross bedded quartz rich sandstone interbedded with organized conglomerate upward into the massive chaotic conglomerates

PETROLOGIC DATA

Rock Number: 1

Rock Type: sandstone
Field Description:

-the sequence upward is cross bedded and graded sands with pebble lags and thin 30 to 50 cm CGLM beds through transition over 40 m where the sand buds thin to 15 to 30 cm and the conglomerates increase to several metrs and become less sorted, coarser and more chaotic
-after 65 m all that remains are rare 10 cm sandy horizons in chaotic boulder conglomerate
-sample of sandstone layer
