Riverside Geyser erupted on the late side, so we were already into the window of Daisy Geyser's eruption (prediction time of one hour window and eruptions about every 2.5 hours). As the skies darkened we hurried over to Daisy hoping it hadn't erupted yet. We were in luck - it hadn't erupted yet (and our Geyser Grand Slam still intact!). We had time to take some pictures of the colorful basin, steaming vents, and dark clouds amassing in the background.
