I'm not an active gazer these days, but was in the Park a lot back in the early 1980s. I've been following the Black Diamond story, did a Google search and came up with these pictures from 2009. Sorry if they have been posted here before, but I was wondering : Are these indeed pictures of a Black Diamond eruption ? If so, they are awfully dramatic. http://www.greateryellowstonescience.org/sites/default/files/references/YS_18_1_Heasler_sm.pdf Bob Johnson Bend Oregon -------------- next part -------------- An HTML attachment was scrubbed...
