A view of Round Geyser in eruption as seen from Geyser Hill, near Depression Geyser. I don't know who took this photo, or remember how I got a copy.
Next are three photos Mary Ann Moss took. Opal was a geyser that she saw several times over the years.
This eruption doesn't look all that big, but note the figure standing on the far overlook at the left. Also, the jet from the big boil is easily well above the rim.
