Three ~continuously-splashing vents on a sightline (from the Fountain overlook platform) just east of / just right of K13's vent. The front vent is a small spouter - one of Deep Blue Geyser's marginal spouters. The other two splashing vents appear to be east-southeast of K13 and just northeast of K13. On all afternoon. Occcasionally would see decent-sized splashing from K13 itself. |

K13 appears "restless", as I've reported many times in previous seasons. Using binoculars, it's actually clear that three different splashing vents are giving the restless behavior appearance. They are almost aligned, in terms of a sightline from the Fountain overlook platform. The front active feature is definitely a Deep Blue marginal blipper, with relatively small spouting. The two active features behind the marginal blipper have larger splashing and may be vents just ESE of K13 and just NE of K13. K12 is also along the same sightline, but I'm hesitant to say it's active at all without unambiguous evidence. |

K13 restless all day. Decent-sized spouting in parts of the afternoon, but not enough to call them discrete eruptions. |
