David Baker: Whale Fall

I read all the poems from Baker’s Whale Fall, but I didn’t fully get them. For example, I like the vibe in “Extinction,” but I am not sure what he’s talking about:

When you are gone they will read your footprints,
if they still read, as they might a poem about love—
wandering in circles, here and there obscured,
washed out in places by weather, sudden landslide.
Keep walking, pilgrim. This is your great tale.

I need to keep learning about poetry by reading more poems.
