Mysterious underwater areas can be found in numerous national
parks and national monuments throughout the United States. The
National Park Service operates a special division, the Submerged
Resources Center, to explore some of the mysteries.
To share its underwater exploration and preservation efforts,
the Park Service has created seven films in partnership with
CuriosityStream, a documentary production and distribution company.
Though longer than most videos featured in “Amusing Monday,” I
believe the science and history revealed in these fascinating films
are well worth the time.
The Submerged Resources Center, which has been in existence more
than 30 years, has been recognized as a leader in documenting,
interpreting and preserving underwater resources. As you will see
in the films, the research teams use some of the most advanced
underwater technologies. Their mission is to support the National
Park Service’s preservation mandate and to enhance public
appreciation, access and protection of these resources. Areas of
focus include archeology, marine survey, underwater imaging and
diving.
I have embedded three videos on this page, but I’m providing the
full list here, with links, also accessible on the National Park
Service’s website called “Underwater
Wonders of the National Parks.”
Devil’s Hole: This unique underwater cave can
be found in Death Valley National Park on the border between
California and Nevada northwest of Las Vegas. The film features a
unique species of fish called the pupfish, which are among the most
endangered species in the world. Assessing and protecting these
fish is a major responsibility of the Park Service. Another good
story with photos and video was featured in
The Desert Sun newspaper of Palm Springs, Calif.
Montezuma Well: Swirling sands at the bottom
of this lake create spooky conditions for divers who cannot find
the bottom and often find themselves sucked into a kind of
quicksand. The “well” can be found within Montezuma Castle National
Monument south of Flagstaff, Ariz. Few creatures can survive in the
waters rich in carbon dioxide and arsenic and fed by pressurized
water vents. But divers are monitoring the populations and
interactions among four species found there: diatoms, amphipods,
snails, non-blood-sucking leaches and water scorpions.
USS Arizona, Part 1: The USS Arizona, which
sank during the attack on Pearl Harbor, is a national memorial to
the 1,177 sailors who went down with the ship. The National Park
Service is responsible for monitoring conditions — including sea
life — in and around the Arizona.
USS Arizona, Part 2: The second video on the
Arizona Memorial features more about the history of the ship and
artifacts still being discovered. Divers are serious about their
solemn roles. For example, World War II survivors of the attack may
choose to be reunited with their shipmates, so urns with their
remains are moved into a special place aboard the sunken
battleship.
Yellowstone Lake: Thermal vents and impressive
geothermal spires are unique to the freshwater habitat of
Yellowstone Lake, which lies in the center of Yellowstone National
Park in Wyoming. A major concern is the survival of the lake’s
native cutthroat trout, which are being consumed by the voracious
lake trout, an invasive species. Mapping the lake’s bottom to
locate the lake trout’s spawning grounds is one idea to help
contain the problem.
Lake Mead: The first national recreation area
in the United States, Lake Mead, which is east of Las Vegas, was
formed by the construction of Hoover Dam in an area known for its
military secrets, including Area 51. In 1948, a B-29 bomber crashed
and sank in the lake while conducting research into a new
navigational concept, which eventually became incorporated into
guidance missile systems. The aluminum aircraft is well preserved
on the bottom of the lake, although it is now encrusted with
invasive quagga mussels, which spread too fast for divers to keep
track of them.
Buck Island: An amazingly productive ecosystem
can be found within Buck Island Reef National Monument in the U.S.
Virgin Islands of the Caribbean. Experts monitoring the reef’s
conditions must experience mixed emotions, as they document the
amazing sea life as well as “bleaching” of the coral reef, portions
of which are dying from disease. Divers have been able to save some
of the corals by chiseling away the infected areas. The National
Park Service also documents the history of the slave trade as it
explores for artifacts from more than 100 slave ships that sank in
the Virgin Islands — including at least two near Buck Island.
