First is Grotto Geyser, actually a group of four different geysers. They are located not far from Old Faithful. Grotto Geyser erupts two to three times a day, but apparently Haynes, the photographer, didn’t stick around long enough to take a photo of it in action.
This is a postcard based on the same photograph and attributing the photo to Haynes. This must be from the same company as a previous postcard whose artist applied a rosy glow as if the photo was taken at sunrise or sunset.

In contrast to Grotto Geyser, Giant Geyser can go for months or years between eruptions. So the photographer, presumably Haynes, did well to catch it at its peak. When it erupts, it is much taller than Old Faithful.

Here is Haynes’ black-and-white photograph on which the above postcard was based. The postcard fails to show the brilliant blue color that led Haynes himself to name the pool Sapphire.
