|I find describing water levels in Congress challenging! The pool is LOW. 2' Below it's high water/mud mark from earlier this summer. It has a vigorous roiling boil on the west end of the pool. It's the color of milk chocolate with dark chocolate swirls on the south end of the pool and has a putrid odor! There are 2 interesting features in the Solfatara area about 30' to the west of Congress pool. 2 areas of boiling springs/liquidy mud pots, each about a foot in diameter and about a foot apart, that are pinkish/orange in color.
