This is a questionable event.

From Juhle (1955): "According to Dall (1894) the March 1867 eruption [of Iliamna] produced a light pumice and ash fall on St. Paul, Kodiak Island 165 miles to the southeast."
This statement is confusing, because Juhle is referencing Dall, 1894, in Science, volume 3. However, volume 3 of Science was published in 1884, and, although there is an article by Dall published in that issue, it does not discuss Iliamna.
Juhle continues with: "I.C. Russell (1897, p. 211 [listed in bibliography as 1910]) writes: 'In the summer of 1895 it was sending out five or six columns of steam and seemed peaceful enough. A few years ago, however, it was in violent eruption and discharged such a profusion of hot dust and lapilli that the timber over hundreds of square miles of tableland was killed.' Unfortunately the source of this information is not given. Perhaps this refers to the March 1867 eruption. The magnitude of the eruption seems somewhat exaggerated. Today only a few cinder lapilli, which may be remnants of this ash fall, can be found in protected topographic depressions at high altitudes."
Miller and others (1998) doubt the veracity of this eruption: "although Coats (1950) lists several reports of 'smoke', and an eruption in 1867, documentation is poor and validity of the reports is questionable. Except for the summit fumarolic activity, it is uncertain and perhaps unlikely that Iliamna Volcano has been historically active."
