Jerry Kiler is the man standing on the lighthouse–and this is from the HSU Special Collections Site describing the source of a collection:
Sub series: 7113HME1-7115HME4 Milton and Edith Hunter Collection I (1999.03.0821-1999.03.0851) [there are a lot of great photos if you click on the collection link].
Milton and Edith married when they were past 50. They had been married before. They shared an unusual history as Edith (Kiler) was a descendant of the first lighthouse keeper of Trinidad, Jeremiah Kiler, and Milton was grandson of Frederick Harrington, the second lighthouse keeper at Trinidad.

Frederick Kiler was in charge at Trinidad from June 30, 1888 to August 7, 1888. His father had served from 1871 to 1888. Frederick was born in 1850 and had assisted his father at the lighthouse. Frederick L. Harrington was lighthouse keeper from 1888 to 1916. Edward Wyberg served until 1925, followed by Malcolm Cady.
