Read "Sea-Memory" at The Eldritch Dark:
This is a beautiful visionary poem, resplendent with the power of the sea, as it haunts the narrator with richly colored imagery derived from gemstones and precious metals.
Interestingly, the first stanza describes the narrator's dreams, while the second stanza references his memories. Taken together, it becomes clear that the wild ocean has had a truly deep impact on the speaker.
One can't help but assume that there is a certain amount of autobiography in "Sea-Memory". CAS spent most of his life in inland California, but we know that he visited coastal parts of the state, such as Carmel and San Francisco. Perhaps those experiences on the edge of the mighty Pacific Ocean stayed vibrantly alive for him all the rest of his days.
