The very beginning, talking about a spiked sun and whittled down ice, makes me think of an icy place at the end of the day before going on to “I hear the bone dice” to, “pale, the recent snow” makes me think of gambling. Then “Fastens like fur to the river” to “Last year.” makes me think of a possible job this person may have. And then the last few lines, “Above the dead valves pines pared,” to “I want you.” makes me think of a man going home, seeing the person he loves. But, I’ve also heard other things where this poem is about missing someone or something, but, whatever, I guess.
