"Rivulose" by A.R. Ammons

You think the ridge hills flowing, breaking
with ups and downs will, though,
building constancy into the black foreground

for each sunset, hold on to you, if dreams
wander, give reality recurrence enough to keep
an image clear, but then you realize, time

going on, that time's residual like the last
ice age's cool still in the rocks, averaged
maybe with the cool of the age before, that

not only are you not being held onto but where
else could time do so well without you,
what is your time where so much time is saved?
