[Geysers] Geyser Activity at Canyon?

[JEFFREY CROSS]

Although the Canyon and Lower Falls are viewed by millions of people each year, the geysers found in the Grand Canyon of the Yellowstone almost never get mentioned anywhere.

I've heard only one comment made in the last 25 years about these geysers, and that was that the name "Phantom Bridge Geyser" was proposed for a geyser in the bottom of the canyon.  Its eruptions sometimes span the Yellowstone River, and appear as a ghostly bridge of spray and steam, hence the name.

Does anyone have recent (or any) information on the thermal features at Canyon?
