| Comments: | Based on runoff, Feather had been on 2-3 minutes when I saw it in eruption at 1902 along with Feather Satellite, Rust, SW Vents, and Cave to 1-2 feet. Mastiff was surging 1-3 feet, then surged 8-10 feet with heavy runoff that flooded India. Mastiff then was between flat and 3 feet until it surged to cone height again, then went flat again, and then dropped at 1905. Bijou came on at 1905 along with B-C Vent, Cave stopped, and Feather and Feather Satellite got weaker. Then Posthole, Posthole Satellite, and Slit came on with Rust and SW Vents still on. Feather and Feather Satellite returned to full strength, then at 1908 there was low vertical water in Giant's cone; surging reached halfway up, then there was one strong surge to the top of the cone before the surging became more angled. SW Vents, Slit, and Rust shut off, followed by Feather Satellite and finally Feather at 1913. Duration probably 13-14m. |
