[5] By 1941, the Historic American Merchant Marine project had collected and deposited the complete plans of Amaranth at the US National Museum.

Amaranth was the fourth deep-sea, cargo-carrying vessel to venture into the newly dredged harbor, where a naval station was planned, having been preceded by the three-masted schooner W.H.

Nielson, was carrying a cargo of coal from Newcastle, New South Wales to San Francisco when she wrecked on the southeastern shore of Jarvis Island.

[1][8] On shore, the Amaranth crew could see the ruins of ten wooden guano-mining buildings, including a two-story house.

The Amaranth's scattered remains were noted and scavenged for many years, and rounded fragments of coal from the ship's hold were still being found on the south beach in the late 1930s.
