Went out to Grand with the expectation of having to wait until dark for the eruption. The pack had nighttime gear, including a light, and dinner. As it turned out, saw Grand start while standing at Sawmill. It was a nice tall start, and noisy. Two bursts but the total duration was under 10 minutes.
Since it was still going to be daylight for over an hour, went down to Fan & Mortar to kill some time. Definitely in a garbage mode, as within a minute or two of River starting, Gold and High were getting continuously with some power. Then it all died down.
