Rocks clatter down as #USGS scientist David Johnston kneels beside the crater water pond to fill sample bottles. He’s trying to figure out why SO2 emissions are so low. Maybe gases are dissolved in water? Analyses reveal no clues.
I love this woman. Our friendship was basically born out of cinnabar. Also, she doesn't give herself enough credit -- she was working towards a graduate degree at the time.
Back during my geology undergrad work, @MindyZuckerman and I did our mineralogy poster on #Cinnabar, and we learned a ton. We can tell you horror stories about makeup usage and why hatters were "mad". So vote for cinnabar, but please, do not lick it.
