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.
No attachments for this geyser.
Baseline does not exist.
