| Comments: | Carolyn Loren reports: "A winter guide Rowan [Laing] noticed black muddy water flowing into the Firehole by the Biscuit bridge went to investigate and found visitors that saw Black Diamond erupt. I spoke with them this morning and what they saw was from the back boardwalk at Biscuit and was they think near the end of the eruption. They were impressed by the very dark muddy water which they estimated at 20 feet tall. The time was about 1305 on 12/26." |
