Columbia Daunted but Still Roils

One way these track run
into the elevator
and onto Mt Hood

Turning east
stopped by wooden fence
dam the beyond
columbia daunted
but stil roils

stunted but strong
regressed to measure and
potential
water spreads
thinner than gold
every fiefdom wants a piece so they
bridge it
dam and tame it

rocks and monuments
observe the folly
silt builds up behind
water cool ahead
moving beyond memories
of drowned villages and
uncovered artifacts
entombed, enshrined
only the tugboats
come close

barge drifting
silos wait
trains slip past
and columbia rolls

Whatcha think?
