The lower part of King's section was much easier to follow than the upper part. This might be in part the result of the topography for beds 14 and higher are exposed on the top of the mountain. Here again there seems to be a change in lithology at the interval of the Hess fossil bed and just above and below - Thus, although we tried to follow the route of the measured section it is possible we missed it in the upper units. The fossil bed is a pretty poor unit here and is not the resistant cliff it is to the west. Fusulinids (often recrystallized) really make up a lot of this interval above and below the Hess fossil bed. PG. 25 7/14/59 With Cooper, Grant, Skinner and Wilde, and Stehli. Collected from Hess ranch horst and from the Word about 1 mile NW of Hill 5779 north of Leonard Mt. Word 1 limestone - 35' - 3 collections. Word first shale Collected 5-2A Word - 35' up. Word first shale Collected 5-2B - 45' up 5-2C - 65' up Limestone becomes more abundant and the upper 50' are 2' to 3' limestone beds - Collected 5 -3A - 15' up. Collected 5-3B - 20' up. --------Total 140'. Word limestone - position of second limestone - Collected 5-4 - ------- 7'. Shale---------------------155' Word - 1' beds of limestone - Collected 5-5A - [near base] Collected 5-5B - 5' up. --------10' [I think this is what the notes mean.] PG. 26 Shale --------- 20' Limestone - Collected 5-6A. ------2' Shale ----- 20'. Limestone - base third Word limestone- Type locality of Paraf, sellardsi according to Skinner. Collected 5-7A. ---- 3'. Shale - 12'. Cephalopod zone - 2' limestones at base of next limestone, medium gray (upper part of third Word limestone[?]) - no fusulinids ------ 65'. The first Word limestone is thinning to the NW - mainly at the top by intertonguing with siliceous shale - The limestones just below Word limestone 2? are fine
