Mammoth Lakes Expansion Notes in Alphabetical Order
Crowley Lake: (See Mammoth Area Fishing) Named after Father Crowley for his tireless
efforts to promote tourism in the Owens
Valley after Los
Angeles drained the area of water, Crowley
Lake is actually a 5,000 acre reservoir,
which filled Long Valley from the Owens River
and the many smaller creeks in the area.
Completed in 1941, the lake supplies water for the domestic consumption
of Los Angeles. The lake is administered by the Los Angeles
Department of Recreation and Parks. Lake Crowley
is perhaps the most prolific trout nursery and resource in the region for fast
growing trout, along with Sacramento
perch. Anglers from southern California converge on
the lake opening day of trout season in staggering numbers so large that I
hesitate in reporting these published figures. Suffice to say close to ten thousands
anglers line the shoreline in years experiencing a mild winter. Upwards of over three hundred boats have been
counted opening day. Some years the lake
thaws early, which produces larger trout.
Some years the lake will not be thawed so call ahead.
Devils Postpile
National Monument; Red’s Meadow and Rainbow Falls
I have combined these
“must see” side trips because the entrance road has driving restrictions. (See driving restrictions below)
The area of the Middle Fork of the San Joaquin River
will delight visitors with spectacular lakes and streams. Within the valley, lush meadows teem with
wildlife and floral displays rival any other scenic spot in the Sierras. Add shimmering water spilling over a basalt cliff
at Rainbow Falls, nearby trails that lead day
hikers and back packers into the Ansel Adams and John Muir Wilderness, and it
is no wonder that over 100,000 visitors a year enter this Sierra shrine. Originally encompassed in Yosemite National Park,
mining and logging lobbyists successfully pressured Congress in removing 500
square miles from the recently established park. The Devils
Postpile was suddenly expelled from the protection of park status. When news spread about the proposal in 1910
to detonate the spiraling vertical basalt columns, and use the rubble for a
rock impoundment downstream, the environmental community was galvanized into
action. The Devil’s Postpile, by
presidential proclamation from President Taft, earned a protective status when
it was declared a national monument in 1911. Reaching the Devils Postpile from
the visitor center is made along a quarter-mile trail that wind along the river
and through stands of lodge-pole pines and fir to the base of the cliff. “Not only does the Monument preserve and
protect the fascinating formations of the Postpile, but it serves as a portal
to the sublime High Sierra backcountry….The Devil Postpile is one of the finest
examples of columnar basalt in the world.
Approximately 55% of the formation’s columns are six-sided.”
(www.nps.gov/depo/)
Rainbow Falls is approximately two miles downstream from
the Devils Postpile National Monument,
and it too is reached by trail. Tumbling
a 101 feet over a sheer wall of rugged basalt, the mist creates prismatic
rainbow displays when the sun climbs above the mountain tops. It is a wonderful place to relax, take
photographs and enjoy a picnic lunch. A
fun way to get to Rainbow
Falls is to ride a
mule-drawn wagon from Red’s Meadow.
Road Restriction:
Mandatory travel restrictions are enforced for the Middle
Fork of the San Joaquin River and the Devils Postpile
National Monument
area. Only campers are allowed to drive
on the road from 7:00 A.M to 7:30 P.M. A
shuttle bus operates repeatedly throughout the day from the Mammoth Mountain
Ski area for visitors during these restricted travel times. “All
visitors accessing the recreational opportunities and activities in the Reds Meadow
Valley are charged a
per-person transportation fee. Fees are collected during the entire
open season and all hours of the day. Fees are used to operate the shuttle
system. If visitors arrive when the station is closed, their fee will be
collected upon their exit from the valley. Passes are available at the Shuttle
Terminal at Mammoth
Mountain Main
Lodge Gondola
Building and also at
Minaret Vista Station for those few exceptions that are not required to ride
the bus.
The shuttle service to Reds Meadow/Devils Postpile began in 1979. The
shuttle was determined necessary to reduce the impact on the environment from
vehicle traffic. The narrow road into the Reds Meadow area serves as the only
access to the San Joaquin River Valley
, the Devils Postpile
National Monument , Rainbow Falls
and 5 trailheads leading into the John Muir and Ansel Adams Wilderness Areas,
including the Pacific Crest Trail and John Muir Trail. The road also allows
access to 186 campsites (6 campgrounds), 4 nature trails, and 2 day use lakes,
Reds Meadow Pack Station and Lodge, and Agnew Meadows Pack Station. Vehicle
use and Exceptions
Excessive vehicle use is the reason for a mandatory shuttle bus. However,
some exceptions are recognized. Following is a list of most exceptions:
- Vehicles entering the valley before
7:00 am , or after 7:30 pm
- Vehicles carrying passengers
with a disabled placard (once in the valley visitors must hike to most
sites)
- Vehicles towing horse
trailers or other livestock
- Campers camping in the Reds
Meadow area
- Overnight Resort Guests
- Administrative vehicles
- Vehicles carrying car top
boats, canoes, kayaks for use in valley
Exceptions are still charged the per person transportation fee.”

Hot Creek Geologic
Site
In the annals of trout fishing lore, Hot Creek is known far
and wide. Downstream from the Hot Creek
State Fish Hatchery, visitors leave their fly rods behind and witness hot gas
vents, boiling water, sky-blue hot
springs and rising steam, which rises to the earth’s
surface from molten lava miles below. Be
prepared for the sulfurous smell of rotten eggs as steam escapes from fumaroles
along the creek. Visitors are cautioned
to stay on designated trails as the ground is unstable. The short trail offers an overlook and an
observation bridge. To reach the hot springs from Highway
395, turn east at the airport exit and follow the signs on Fish Hatchery Road, which is three miles
south of Mammoth Junction. Drive 2.5
miles on a gravel road to the parking area.
Hot Creek State Fish
Hatchery raises a couple of million trout annually to be stocked
locally. Considered to be one of the
largest hatcheries in the state, the Hot Creek Hatchery also produces over 20
million trout eggs for hatcheries throughout the state.
Inyo Craters
The Inyo Craters are older than the Mono Craters. Looking like a funnel depression stuck in a
mountain, the Inyo Craters are
examples of super-heated steam explosions when ground water comes in contact
with rising magma. Referred to as
phreatic eruptions, the magma never reaches the surface. Radio carbon dating of wood debris sets the
time of activity at over 600 years ago.
The two Inyo craters pits are 600 feet in diameter and hold water at the
bottom of the funnel. The craters may be
reached by trail through a Jeffrey pine forest which ends at a picnic site. To reach the trail from Mammoth Lakes,
take the Mammoth Scenic Loop Road. Look for the signed entrance to Inyo Craters
and continue one mile to the parking area.
Mammoth Lakes (See Camping and Fishing Section)
Mammoth-Mono
Geological Tour (The Mammoth Ranger District Headquarters offers a pamphlet
entitled, “Craters – Cones- Coulees” for a self-guided tour of 10 geological
sites.) You are mistaken if you believe
that visiting the area’s caldera, an area approximately 10 by 20 miles, will be
a stroll down memory lane when the last eruption occurred 100,000 years
ago. The Mono-Long Valley Caldera is
alive and well. So, what are the odds of
an eruption during your planned visit.
Scientists on staff at the U.S Geological Survey predict that the
probability of any activity is about 1%.
In other words, stick around for another 100,000 years for the
fireworks. The most recent eruptions
created the hills surrounding Mammoth
Lakes, a mere 100,000
years ago. Keep in mind, however, that
the entire Mammoth and Mono
Basin sees isolated
pockets of activity outside the Long Valley Area. As recent as 250 years ago, an eruption on Paoha Island
in Mono Lake shook the area.
The study of geology is not the study of ancient
history. It is the study of Mother Earth
in her slow, meticulous transformation of our planet. Should an unthinkable and unpredictable, less
than catastrophic, eruption take place during your visit and in close proximity to where you stand, take
heart from the fact that lava flows “rarely move faster than a brisk walk.” It
will be the pyroclastic blast of hot ash venting at speeds “greater than 100
miles an hour” that will get you! I
exaggerate, of course. Scientists
predict that the next eruption will more than likely be small, and it could be
limited to that of an explosive steam kettle, with the molten magma activity
safely under the ground as it vaporizes underground water in its struggle to
reach the surface. When sub-surface gas
is pushed up just beneath the earth’s crust, and it is touched off by a
finger-like vein of molten rock, “stuff” happens. It is precisely this rising finger of hot
molten rock that keeps the USGS busy monitoring the area. In 1980-1982 scientists noticed a slight
uplift of the ground surface in the Long Valley Caldera, as the magma and a
finger-like projection pushed upwards along the south wall of the caldera.
The self-guided tour of the geological wonders around the
Mammoth area, including a trip to the Hot Creek Geological Site, is an
important part in understanding the region.

Mammoth Mines
Mammoth Mountain Ski
Area: Encompassing 3,500 acres, 150
trails, 29 ski lifts and three full service slope-side lodges, Mammoth Mountain
is the quintessential ski resort in the eastern Sierra Mountains.
Minaret Vista

Mammoth Mountain
Located a short distance west of the Mammoth Mountain Ski
Resort on Minaret Road, the Minaret Vista at the top of the pass affords an
impressive view of the headwaters of the Middle Fork of the San Joaquin River,
the Ritter Mountain Range and the jagged Minarets across the valley floor. A self-guided tour provides signed
information on the geology and plant life in the area from the picnic area and
Deadman Pass Trailhead.
Obsidian Dome
Obsidian, prized by the Indians for making spearheads and
arrowheads, is a black, glass-like creation from lava that cooled rapidly after
a surface eruption. Thousands of years
after the caldera was formed, domes were created from magma pressure far
below. The resulting ground swell forms
a resurgent dome. Think of the Obsidian
Dome as a magma after-thought or burp.
If you have visited Mammoth Hot Springs Geothermal area, you can imagine
what that burp smelled like!
Whitmore Hot Springs
Operated by Mammoth
Lakes, the pool is
regulated at 80-degrees from a nearby hot spring. Open to the public, Whitmore Hot Springs pool
is located one mile of Highway 395 on Benton
Crossing Road, just before the Mammoth Airport.
