A federal appeals panel rejects a challenge by environmentalists
against exploratory drilling for geothermal energy near Crater
Lake. The Interior Board decided that the BLM had prepared an
adequate environmental analysis allowing California Energy to
drill two test holes on the Park’s east boundary.
A federal judge stops logging on a 1,000 acre tract in near the

The MT reports that the Park Service has decided to close the
Lodge. Superintendent Benton claimed, “The dead weight of the
building would cause the Great Hall to collapse. The decision
was made purely on the basis of public safety.” The 1989 fiscal
budget appropriates $1.76 for Lodge planning. The Lodge’s
closure speeds along plans and money appropriation and design
work for the building’s reconstruction. Public support for a
rehabilitated Lodge continues to drive Congressional backing for
the entire redevelopment package.
Morton Clark of Grants Pass, loses the engine of his Waco UPF-7
biplane trainer while flying over Crater Lake. The engine dies
completely. “It was 2 to 3 minutes before I could get the engine
started again, and all the time, my wife and I are circling over
the lake wondering how cold the water was.” The Clarks dropped
1500 feet-even with the Rim before the engine was restarted.

A mysterious aqua-blue pool of a strange liquid is discovered at
the bottom of Crater Lake. The pool measures about 2 meters wide
by 8 feet long. It is near the lush white and orange bacterial
mats found last summer. There is a yellow rim surrounding the
pool. The temperature of the pool was about 40.1 degrees F (4.5
C), one degree warmer than the surrounding Lake water. A new
mite, called the Crater Lake mite was discovered the previous
week. The mite is a new species that eats algae. Algae lives in
the Lake up to 450 beneath the surface. Below 150 feet the Lake
temperature only changes half a degree.
Deep Rover measures water temperatures of 17.7 degrees C while
probing bacterial mats at the bottom of the Crater Lake. That
temperature is 14.2 degrees C higher than the surrounding Lake
water. The new temperature reading is also higher than
summertime surface temperatures.
Summer Conclusion of Lake Exploration with Deep Rover: The Blue
pools (Llao’s Bathtubs) are 10 times more saline then the
surrounding Lake water. Blue pools within a blue lake. The
temperature variation ranges from 38 degrees to 68 degrees
inside the bacteria mats, which are 3 - 4 inches deep and of
The Hydro thermal inflow is estimated at 200 - 300 liters per
second. Heat input, measured at 15 - 20 mega watts, is spread
out immediately over a large area. Thermoclines create a lake
water turnover every 1 - 4 years.
30 foot chimney-like spires found extending upward from the
bottom of the Lake, near the sides. Most likely fossilized
remains of extinct hot springs. On the Crater wall is a 300 foot
wide band of moss beginning 100 feet below the surface,
completely encircling the caldera. Some mosses discovered are
found only in Crater Lake.
Only 2% of the caldera floor and walls were visually
explored. Midge fly worms (larva) were found crawling in the
light gray pumice sediment on the Lake floor, leaving behind a
crawl trail behind. During the summer the larva change to the
pupa stage, float 2,000 feet up to the surface, where they
become midge flies. Living only two or three days, the midges
lay eggs on the Lake surface and die. The eggs sink to the
bottom of the Lake, where they hatch and begin the cycle all
Final Conclusions of Deep Rover’s Lake Survey: As a result of
the past three years, we concluded that there are inputs of
hydrothermal fluids in the bottom of Crater Lake. The dissolved
materials associated with these thermally and chemically
enriched fluids, coupled with the overall hydrologic balances,
control the observed chemical composite of the lake. Because
hydrothermal input dominates the material fluxes of most
chemical into Crater Lake, the hydro thermal process is highly
significant. Furthermore, the geothermal inputs have a direct
effect on the density structure of the deep lake and
consequently the rate of heat, salt and nutrients redistributed.
Only 130 bull trout found in Sun Creek. A 1947 survey found
Park Officials express concern that Crater Lake has become an
“island of trees” in a surrounding sea of forest clear
cuts. “Our security blank for the past 87 years of being
surrounded by three national forests has been stripped away and
this is having an effect on the park’s wildlife.”
