Algal limestone resting on top of Mulberry Member, Bandera Formation

Outcrop on east side of I-170 showing rock units in the Bandera
Formation exposed at this site. The lenticular algal limestone is in the
lowermost part of the conglomerate and limestone unit, and rests
directly on greenish gray claystone of the Mulberry Member. It
may correlate with the Farlington Limestone Bed in the western outcrop
belt. A star marks the place where the slab was obtained.
