History
The Canadian Pacific Railway's SS Princess Sophia grounded on Vanderbilt Reef to the north early in the morning of October 24, 1918, in the midst of a snowstorm. The United States Lighthouse Service tender Cedar, captained by John W. Ledbetter, had taken up shelter at a cove of Benjamin Island when it received word of the passenger liner's plight at 14:00 that day. The Cedar left Benjamin Island almost immediately but did not reach the reef until 22:00.

Wildlife
Humpback whales and Steller sea lions live in the area of the island. A cow moose was noted on the island in 2005.

A joint project between the National Marine Fisheries Service and the University of Alaska Fairbanks placed cameras on the island for the purposes of studying the sea lions.
