... back to Norris to take some temps...it’s good to be back to the basin & see all the changes that have occurred over the past month & a half.
There was an earthquake measuring ~3 on the Richter centered in the Crazies a few days ago. This may account for the increased turbidity in many of the features. Also the amount of H2O outflow from the Back Basin particularly seems to be much higher than it was this summer. This could be partially due to snow melt as we have 15-20 inches on the ground now, but not entirely I don’t think. Anyway...Blue Mud Steam Vent Gray slightly turbid H2O – vigorous boil to 1½’ in center vent – superheated 206° [generic day time] |
