Saddle Creek bed is finely exposed 1 to 2 miles south of mouth of Saddle Creek [McCulloch County, central Texas]. On north side of Colorado River it remains north of the river from north of mouth of Saddle Creek to northwest of Waldrip. [Age is Pennsylvanian.]

Pg. 66 (fig. 1), 91. Saddle Creek formation of Pueblo group. Rank raised to formation and reallocated to the Pueblo here redefined, given group status and assigned to the Permian. [Expanded to include Waldrip Nos. 2 and 3 limestone beds of Plummer and Moore (1922).] Underlies Stockwether formation. Redefined Pennsylvanian-Permian boundary is placed at disconformity in Harpersville formation above Waldrip-Newcastle coal zone about 40 to 150 feet below Saddle Creek limestone.

Sheet 2. Saddle Creek limestone member of Pueblo formation. Described in Colorado River Valley as limestone member of Pueblo formation. Consists of thin iiregular layers of brittle fine-grained blue-gray limetone 4 to 5 feet thick. Underlies Camp Creek shale member; overlies Waldrip shale member [rocks previously included in Saddle Creek formation by Cheney]. Age is Permian.
