This limestone unit unconformably overlies Catalina Schist and is overlain by Upper Miocene andesite. Two small deposits of fossiliferous limestone are located on the flanks of Mt. Banning (439 m ) and Bald Peak (427 m ) on the south side of Bullrush Canyon (Fig. 1). These limestones overlie earlier Miocene volcanics. They are intercalated by andesitic tuffs and lapilli and overlain by andesitic lavas of Upper Miocene age. A tuffaceous diat- omite deposit, extending from sea level at Big Fisherman Cove to about 150 m at Empire Quarry (Fig. 1), is intercalated by beds of lapilli and capped by Upper Miocene andesitic volcanics. Defined Terraces Apparent terraces were observed and described by Smith (1847) from the upper sections of Avalon Canyon (Fig. 1). Rounded pebbles that he found on the surface of apparently terraced areas in the vicinity of Little Harbor were interpreted as Table 1.
