| 16213 | 20 Sep 2020 @ 1829 | --- | DanS | Reported eruption earlier this week was likely incorrect. Small depression where I believe Radiator would erupt is between Bonita and Zigzag only lightly steaming and no signs of having water recently. |
| 13660 | 12 Sep 2019 @ 1133 | --- | Micah Kipple | I belive these entries might be a case of mistaken identity. "Zig Zag Spring" is the feature that reactivated this year in the Daisy group. Radiator is closer to daisy and showed no signs of reactivation but I will see if I can get eyes on it. |
