37905 31 Oct 2024 @ 1357 --- MAB Little depression still visible but appears the same size as two days ago - there may be more discoloration of the gravels but hard to tell in the flat light and snow - we might not know if it's back until Spring
37836 29 Oct 2024 @ 1648 --- MAB In Sundays pics I could see a darkened area I didn't notice in person - today it was a basketball sized shallow depression with darker gravels - I'm guessing NBK7 will be back soon!
37801 27 Oct 2024 @ 1341 --- MAB saw heat with FLIR - nothing observable at ground level
37247 29 Sep 2024 @ 0926 --- TSBryan nothing to see in the area

22905 27 Jul 2022 @ 1613 --- MAB NBK7 still hiding under dry gravels - possible slight depression will compare photos

20300 04 Nov 2021 @ 1213 --- MAB Periodic all summer - now just 1/4 full & blipping - didn't get fuller or stop and drain - closed intervals last week for reference
37100 01 Sep 2017 @ 0000 --- research-mab ~exact date unknown~ ~160 ft North of Puff n Stuff, ~73 ft South of NBK-8, ~20 ft west of dirt trail. First spotted erupting by Steve Eide Labor Day weekend 2017. {Sput Vol 31 #5}
20443 30 Jun 1994 @ 1200 --- research-mab {Sizzle Pot in NBK-7 area} 6/30 A large Basin wide water level drop today. Small vent below original Black Growler vent is dry. Crackling Lake Spring down. Black Pit down. “Sizzle Pot” dry. Black Hermit down. Green Dragon down. Hydrophane down. Gray Lakes down. Phillips Cauldron down. Blue Mud Steam vent down. You get the idea. I think (Guess) that we have just finished a weak disturbance.[generic day time]
29281 08 Jun 1994 @ 1200 --- research-mab 6/8/1994 no time noted - Roving this morning and noticed new vents. Are these new? vents across from “sizzle pot”, they look like ground collapsed and there’s a little steam but no water visible. {NOTE probably more south of NBK7 but worth noting - mab}
