By getting out at the eight hour mark, only ended up waiting for Grand for an hour. It was cold and clear, so the moon was bright. The One Burst Grand eruption was short enough that it could've had a second burst, but the slowing down during the final minute seemed like an indication that once it ended, Grand wasn't going to restart.<\/p>\n\n\n\n

Ended up waiting for about 1-1\/2 hours before the start of a West Triplet eruption, then we needed to wait until West Triplet was nearing the end of its eruption before we got another One Burst Grand eruption.<\/p>\n\n\n\n
This eruption had a definite false pause around the nine minute mark before its sudden resumption of activity for another 1-1\/3 minutes. West Triplet quit at about the same time as Grand, and Rift still hasn't made an appearance in several days.<\/p>\n\n\n\n

As I approached the signboards and junction by the lift station, I noticed three deer right next to the bike trail. One ran across the trail into the trees, while the other two stared at me for a few moments, then went bounding off into the meadow toward Old Faithful and Geyser Hill.<\/p>\n\n\n\n
I had just tied down my bike at the bikerack near Castle, and was walking toward Crested Pool when Castle started to erupt. It being a windy day, I quickly went the rest of the way toward Tilt to watch what turned out to be the second major eruption of the day. By that time I'd already seen that Rift was in eruption.<\/p>\n\n\n\n
Rift erupted for another hour. Two Turban eruption intervals after Rift had quit, Turban had a strong, but short eruption. The next interval was short, and there was little overflow from Grand. So it wasn't a total surprise when the next Turban eruption started strongly. Others waiting for Grand were illuminating it, and I could see at least one boop before the One Burst Grand eruption started. Once again, we got an eruption lasting less than ten minutes with no attempt at a second burst.<\/p>\n\n\n\n
