7-5-2018 MONARCH BBEV 1201 See Note under Steamboat
Porcelain Basin still very active, but appears drier. Congress pool down 4-6" from yesterday, still boiling vigorously. Emerald Springs and Monarch runoff appears to have increased. Monarch geyser crater has clearer water and much fuller. Corperal boiling, runoff wet. Cistern did not look any different, boiling steadily, just at overflow. Emerald Springs is still cloudy but with noticeably less boiling.
