“…Fabric-selective burrow porosity and not-fabric-selective bedding plane and fracture porosity are the primary porosity types identified in the field, although some cave development has been observed, likely caused by the intersection of fractures with bedding planes. Most of the observed Camp Bullis HSU has little solution enlargement along fractures and is a confining unit except where caves are present (Clark, 2004;Clark and Morris, 2015).…”

“…It contains fabricselective interparticle, moldic (box work), and breccia porosity (table 1, sheet 1). This HSU appears to divert the downward percolation of groundwater laterally to discharge at springs and seeps (Clark, 2004;Clark and others, 2009). …”

“…The fossiliferous HSU contains some fabric-selective moldic porosity. Not-fabric-selective porosity is generally fracture and cave porosity occurring near the top of the unit (Clark, 2004). This HSU is considered a confining unit (Clark, 2003;Clark and others, 2009).…”

“…1, sheet 1). The unit intercepts the downward percolation of groundwater and diverts water laterally along the contact with the underlying Bulverde HSU, discharging it as springs and seeps (Clark, 2004;Clark and others, 2009). …”

“…In the northern Bexar County area, the Upper Member of the Glen Rose Limestone was subdivided into five informal HSUs (named A through E from top to bottom) to better describe the unit's hydrologic properties (Clark, 2003(Clark, , 2004. These HSUs were mapped in northern Bexar County and renamed as (top to bottom) cavernous, Camp Bullis, upper evaporite, fossiliferous, and lower evaporite, respectively others, 2009, 2011;Blome and Clark, 2014).…”
