Nobody has ever seen wind, only what it does to other things, and Pamela Hobart Carter builds her poem on that fact. "Surface Evidence" reads like a field report. Judging by the imagery, the speaker stands at the edge of a marsh and logs whatever the water's skin reveals. The first line, "On water's surface evidence of wind," gives the legal-sounding title its meaning, and from there the poem collects exhibits.
The collecting is done by the word "also," which appears five times and works like an eye moving along the shoreline, noticing one thing and then the next. The list starts in nature: the "identical twins / of marsh grasses upside-down," reflections imagined as family, each "a darker tinge" than the original. Then comes "marbleized rainbow slicks / in quiets by black mud." The phrase is lovely, but a slick is usually oil, so beauty and pollution sit inside the same image. "Quiets" is also an odd plural noun, as though stillness came in small pockets. After that the language goes flat on purpose: "a stick," "a white plastic bag." No adjective tells us how to feel. The list ends on a deadpan joke: "red words say Thank You." The only written message in this landscape is a shop's mass-produced politeness, addressed to a customer and delivered to a swamp.
The second stanza turns from the objects to the sky that holds them. Sky "rides" on the water, a verb that makes the reflection effortless, and it "perpetuates palette / without weight or repercussion." That phrase is the poem's quiet hinge. A reflection costs nothing and leaves nothing behind. The bag, by implication, is different, though the poem never says so. It lets the contrast work on its own. The sounds support the idea: "spreads sky grey to swamp water" hisses and slides, as if colour were being brushed across the surface.
Then the poem becomes a picture. After the word "stripes," the page stacks four capitalised words:
SKY
LAND
LAND
SKY
It is a palindrome, and it is also the pond. The doubled LAND marks the waterline, where the shore meets its own reflection, and the reader's eye does what the water does and flips the scene. Even the loose, staggered indentation of the lines suggests things drifting at different distances from the bank.
Right after the diagram comes a dash and a small pun: "—sky lies / also floats / below land." The sky in the water is "lying" in the sense of resting, but it is also lying in the sense of deceiving, since it is a convincing copy of something far above. The dash makes the line sound like a speaker catching herself mid-observation.
There is no rhyme and almost no punctuation, so nothing closes off the looking. The rhythm is uneven. Short fragments such as "also a stick" slow the pace to a halt, and longer lines glide on their s-sounds. The word "surface" returns three times, and each time it is both a literal skin of water and a hint that we may be seeing only the top layer of something.
The final "Thank you" is the most interesting choice. The capital Y has gone, and so has the red. What was printed on a bag is now a line of the poet's own, quieter and ambiguous. It could be sarcasm aimed at the litter, or real gratitude for the scene, or both at once. The poem declines to say.
That refusal is much of what makes it worth reading. It treats a plastic bag as one more thing the wind and water have brought into view, in the same list as the grasses. The environmental point arrives through attention, with no lecture. The title's word "evidence" suggests that careful looking is itself a form of moral seriousness: if you describe a marsh honestly, the human mess shows up in the picture with the sky.
