Inner Space

a guide aims her flashlight
at the borehole drilled
half a century before

the build of I-35, below
ground it’s twenty degrees cooler
than the blazing temps out there

the cavern where my Texan mate
takes me to find relief from heat, beneath
a canopy of pencil-thin soda straw stalactites

the Permian floodwater
maze that claimed the lives
of Ice Age species, mammoth

armadillo and sabre-toothed cat,
swamped in quicksand,
a pyramid of bat guano piled high

on the grotto floor, grows taller
with time, past the talus
cone of bone sink I spot

a crumbling tusk,
pass my tongue over a back
molar claimed by dental caries

capped one month ago
in gold, what relics what
remains hereafter
