Lone Pine School – Come properly
dressed for all kinds of weather. It
snowed two days before our
September fieldtrip. We played in
the snow rather than hiking trails.

into the
Rogue River just
below
the Natural Bridge.

Second Stop – Godfrey Glen A glaciated valley filled in with a pyroclastic flow

Dressed for winter in
September..

Godfrey Glen - Can you find the missing mountain?

3rd Stop – The Watchman – are you ready for lunch at 8,025 feet?
Weather permitting. Pack it in / Pack it out! Bring a jacket, it can be windy.

Let’s get started – The Crater Rim Run

Hiking up the Watchman in July
back in the day when it used to
snow at Crater Lake. Hike led by
Ranger Larry Smith.

The Watchman Fire Lookout built in 1932
Elevation: 8025 feet

2,000 feet straight
down to the Lake.
Look at those
polished boots!

It was so snowy there was no
place to sit for lunch.

The wind’s
beginning to
blow!!!

Why does the Watchman Tower have copper wires leading down to the ground?

Why is there so
much copper
wire this high in
the sky?

4th Stop – Cleetwood Cove Trail
1.2 miles down to the water
Elevation gain of 656 feet

First the safety talk. No running on the trail. No rock throwing. No trail cutting.
Llao Rock in the background.

Beware of alligators swimming in Crater Lake!

You are looking into the purest and clearest lake in the world!

Heading out to pick up the tour boats.

The yellow floating “scum” is actually millions of pine pollen grains.

Pine pollen - Natural polution – It floats for a few weeks and then water logs and sinks.

Cleetwood Cove – Notice the row boats that used to be available for rent. But no more.

During the summers of 1975 and 1976 Crater Lake rose enough to
completely cover the dock at Cleetwood Cove. The Lake rises and falls
2 – 5 feet each year depending on precipitation.

Heading for the three-hole
Comfort Station around the corner.

It poured rain on these kids down at Cleetwood Cove. They were soaked.

Oh the burn! – climbing from 6,175 feet up to 6,831 feet.

5th Stop – Sinnott Memorial Overlook
1,000 feet straight down to the water while
hugging onto a sheer cliff!

This is the way lady rangers used to dress. The high heels worked well in the soft pumice.

The May
1915
eruption of
Mt. Lassen
as seen
from
downtown
Redbluff,
California.

The climactic eruption of Mt. Mazama began with a towering column of pumice
and ash rising from a vent located northeast of the summit, which resulted in
pumice deposits as thick as two inches as far away as Alberta, Canada.

This blue sea of silence draws us into its spell and forever changes the way we view
ourselves as we try to understand the awesome forces that created this famous place. We
realize that we cannot improve upon it. We feel a commitment to protect the integrity of
such places. We need to leave Crater Lake just the way it is, so that it may continue to
inspire us.” Ron Warfield, Author, former Crater Lake Park Ranger.

Over 3,000 people died on August 24, AD 79.

Pompeii was rediscovered in 1748. The soft ash allowed easy digging.

Over 1,000 plaster body casts have been made.

avalanches/pyroclastic flows of volcanic ash from Vesuvius in AD 79 completely
covered the prosperous city of Pompeii, killing thousands of people.

The island of Vulcano is about 18 miles off the coast of the Italian “boot toe”. Named after
the Roman god, Vulcan. The ancient Romans believed it to be the chimney of the fire god
Vulcan's workshop. It is from this island’s name that we get the word “Volcano”. The island
is made up of several volcanoes. The last eruption was in 1890.

Mount St. Helens certainly reminds us of the power of nature, and we can certainly see that in
the evidence of the 1980 eruption that's all around us, ... And here we have an opportunity to
understand the forces that lie beneath our feet.

“To say that this wonderful lake is grand, beyond description, is to give an idea of its
magnificence. Everyone gazes at it in almost tearful astonishment.”
- Jim Sutton, Editor, Jacksonville - Oregon Sentinel newspaper, 1869 and “Crater Lake” namer.

June 1971 Park Headquarters. Annual snowfall at Crater Lake has dropped from 600
inches (50 feet) to 196 inches in 2015 (17 feet). But precipitation was normal at 68 in.

Mt. Everest is looking out the second story window.

Winter 2014 – 2015 Only 196 inches of snow.

Charlie True
drove the first
car to the Rim
of Crater Lake
on August 14,
1907. The trip
took four days
from Medford.
It was a brand
new REO car,
which
eventually
became the
Oldsmobile.

“Jeff finds a

Crater Lake
bears had

Lloyd Smith attempting to feed a bear at the Park’s garbage dump. Some days we would
see as many at 20 bears feeding off the garbage. The dump has since been closed.

A lard bucket found at the dump. Don’t stick your nose into other people’s business.

Is this safe? The sign reads, “DANGER! KEEP BACK!”

These folks were lucky, they climbed back over the rock wall uninjured. Unlike so many others .

12 people died this
year from
taking Selfies by
backing over cliffs,
walking into traffic or
by driving into trees.
Yes, people do take
selfies while driving!

It“It is 3,000 feet to the BOTTOM…And no undertaker to
meet you. TAKE NO CHANCES. There is a difference
between bravery and just plain ORDINARY FOOLISHNESS.”

in 1988-1989 a manned, one person
submarine was used to explore the
bottom of the lake. The underwater
exploration found a number of
hydrothermal vents on the bottom of
the lake and along the caldera wall
and strange "gardens" of yellow-gold
bacteria.
Scientists also found that
light penetrates more
deeply into this lake than in
any other lake in the world.

Are there fish in Crater Lake?

When first discovered, Crater Lake had
no fish. In 1888 - 35 rainbow trout were
dumped into the lake.
Eventually over 1.7 million fish were
poured into Crater Lake. Lake stocking
ceased in 1940.
Only rainbow trout and kokanee salmon
have survivied.
You can fish in Crater Lake without a
fishing license.

The boy is Greg
Tinseth with a
nice rainbow
trout and 5
kokanee salmon.
Kokanee are land
locked within the
waters of Crater
Lake. Without a
trip to the ocean
they stay very
small.

Crayfish are not native to
Crater Lake. They were
introduced 100 years ago to
provide food for the fish that
were introduced into the lake
130 years ago. Both non native
introductions have upset the
pristine balance of Crater Lake.
Crayfish now infest 90 % of the
lakeshore.

In 1924 Crater Lake froze over. One of only two times in 100 years.

In 1949 Crater Lake froze over for the second time & was frozen for nearly 3 months.

March 1949 – Two park rangers skied over to Wizard Island.

The word “roof-alanche” was invented at Crater Lake. A dog was killed by a roof-alanche
several years ago while being walked by its master. This car was almost “killed”.

Get up and let’s go
racing on our
snowshoes!

Find the Phantom Ship. See now why it is called a “phantom”?

The Old Man of the Lake is a 30-foot
tall hemlock stump that bobs and
floats vertically in Crater Lake, and
has since at least 1896. Scientists
have studied the stump for over 100
years, chalking its longevity and
oddity up to Crater Lake’s ice cold,
clear, clean water. During one month
in 1938, it is noted, the Old Man
traveled at least 62.1 miles with the
ebb and flow of the lake.
The lake water is so clear the full
length of the Old Man is visible.

The Old Man of the Lake. This up-right floating hemlock log has been cruising Crater Lake for
over 120 years. “He” travels about 20 miles a month. Pushed by the wind.

It is now illegal to climb
onto the Old Man of the
Lake because the top is
rotting.

The Lady of the Woods was
carved out of solid lava rock
by Dr. Russell Bush in 1917.
Later on when it was
“discovered”, people thought
it was the mummy of an
Indian woman encased in a
pumice flow from Mt.
Mazama.
“Older than the pyramids of
Egypt”, they claimed.

A major disaster. The boathouse burns on Wizard Island. 1972

The boathouse on Wizard Island burned far into the night. The fire crew can be seen arriving
by boat. The boat being built on the Island can be seen sitting near the shore.

These towering needle-like
formations of rock, called fossil
fumaroles, projecting from the
Sand Creek Canyon floor, were
formed under sheets of volcanic
pumice that preceded Mazama's
collapse filling in a glacier-
carved valley.
As the surface of the hot pumice
cooled over the years, steam
and gases were released by the
hot rocks underneath through
vents and tubes that were
welded into cement hardness by
their passage. These ancient
vents now stand alone due to
the erosion of the surrounding
softer materials.

While taking in the awesome
beauty of Crater Lake, this

was one lucky lady!

“My owner told me I had to wear a helmet.”

The first boats placed in
Crater Lake were slid down
the Caldera.

The Cleetwood – the first scientific boat on the Lake – August 1886. Using a reel of piano
wire the crew measured the Lake’s depth at 1996 feet. The 2nd deepest lake in the world at
that time. Eventually, using sonar in 2000, the Lake was measured at 1943 feet.

Over the years,
boats on Crater
Lake have been
slid down the
rim, built on
the island, and
flown in by
helicopter.
Most of the
early boats
were crushed
by heavy
snows. Finally
strong boat
houses were
built keeping
some of the
boats on the
Lake for 40
years.

National Park about
1910.

Sometimes the roads were so bad the cars would just fall apart.

There was so much snow during the winter of 1983 that Ranger
Larry Smith was doing snowshoe hikes in August!
