Activity at Mount Blackburn was reported in an Associated Press article published March 26, 1930, but this activity is probably attributable to Mount Wrangell rather than Mount Blackburn. From the article: "Mount Blackburn is erupting again. Chitina residents report that the eruption is spectacular, not to mention huge columns of black smoke."
From Motyka (1983): "Another short eruption is reported to have occurred on April 6, 1930. Again documented by photographs from Chitina, billowy white plumes were observed rising high above the West Crater [see figure 8 in original text for photograph of plume].
