Black Pool, northern Lower Group, West Thumb Geyser Basin, Yellowstone Hotspot, northwestern Wyoming, USA in August 2011 (looking ~SE).
Black Pool is a very hot, moderately deep, irregularly-outlined, and intensely blue- to deep turquoise-colored. It was formerly a deep greenish-black color, from the presence of yellowish extremophile bacterial mats on the pool walls and floor. Subsequent natural heating of this feature has knocked out most of the bacterial mats. Abundant, suspended, <0.5µ-sized, colloidal silica particles are responsible for the blue coloration of the water.
In 1991 and 1992, Black Pool had atypical activity, coinciding with activity at nearby Abyss Pool (see above). One explosive eruption here in August 1991 involved the forceful detachment and nearby deposition of geyserite clasts. Boiling water domes up to 3 feet high were present in the pool after that eruption, accompanied by significant overflow.
Small eruptions also occurred at Black Pool in 1992.
The above photo shows the edge of Black Pool in August 2011 - nicely formed, loose and coalesced nodules of grayish-colored geyserite are present in the shallowest portions of the Black Pool. The brownish-black areas are bacterial mats.
This is one of my personal favorite of my photos. It was taken in the Dominican Republic about 2 years ago. My son and I traveled there for a week as a college graduation present to myself, this was before I met my husband. We spent a week flopped by the pool, taking photos, and reading books. This was a little peice of joy I got to bring home and frame quite large. :)
Feeling a little abstract and testing the underwater housing. I have ALOT to learn about shooting underwater it seems. Like starting with goggles!
This is the infinity pool at ME hotel in Cancun. It was really nice, but we only spent the last night there. It was probably a little too nice actually.
I should have taken a "before" shot. Dad's pool was left unattended for a little too long and was filled with some really nasty algae. I've been cleaning it this week and you can see it's still a little foggy. The duck is a chlorine dispenser. I bought it thinking of DJ.
There really is a pool table underneath, in transit between locations long enough to fill will rain. A nice case of nominative determinism . . .
Surprise Pool, Great Fountain Group, Lower Geyser Basin, Yellowstone Hotspot, northwestern Wyoming, USA in August 2011 (looking ~NNW).
Above: This overflowing hot spring has an intense blackish-blue to blackish-green color. Vigorous boiling occurs along portions of the pool border and sometimes near the center. Surprise Pool does not have geyser eruptions.
Below: Surprise Pool’s drainage channel heads ~WSW and is bordered by irregularly wavy geyserite crusts. The deep yellowish and orangish-brown colored areas have extremophile bacterial mats.
