Landscape Born
in Volcanic Fury
The Lava Beds is a rugged plain of lava and
sagebrush, punctuated by cinder cones, and rich
with geologic curiosities, archeological sites,
unique plant communities, and wildlife. Located
between the summit of the Medicine Lake volcano and
the Tule Lake basin, its 46,000 acres link the
alpine and high desert environments. Lava Beds
attracts history buffs, cave explorers, wildlife
enthusiasts, bird watchers, campers, geology
students, photographers, and anyone seeking
wilderness.
Lava Beds is a treat for any student of volcanic
phenomena. The landscape is dotted with spatter
cones, lava flows, collapse trenches, chimneys,
fissures, and cinder cones. This north flank of the
Medicine Lake shield volcano is made up of layer
upon layer of lava flows, built up over millions of
years. Many of the flows came from Mammoth Crater,
a huge pit located within the park boundary. Rivers
of hot lava emanating from the crater crusted over,
partially drained and collapsed, leaving sinuous
chains of lava tube caves. Exploring these caves is
a highlight of the visitor experience.

Life Abounds in a
Seemingly Barren Wasteland
Wildlife abounds at Lava Beds. Take a hike and
you are likely to see mule deer, pronghorn
antelope, cougar footprints, and perhaps a bald
eagle soaring overhead. Wintering bald eagles
shelter in the Lava Beds as they forage here and on
the shore of adjacent Tule Lake, before returning
to breeding grounds in Canada and Alaska. Once an
endangered species, these magnificent birds have
thrived in the protected environment of Lava Beds
and adjacent Tule Lake.
The caves are home to two species of rare bat,
the Townsends Big-Eared Bat and the Mexican
Free-Tailed Bat. The bat colonies are a vital
remnant of the once more extensive bat colonies in
the region. Much of their habitat has been lost to
nearby development and other human activities over
the past hundred years. Although protected, the
bats at Lava Beds are not completely safe from
harm. Disturbance by cave visitors, exposure to
environmental pollutants, and loss of feeding
grounds outside the monument boundaries all pose
potential threats.

Prehistoric
Mystery
As long as 4000 years ago, an ancient people
carved rock art in the shores of Tule Lake, and
painted symbols in the caves of the Lava Beds.
Their artifacts are found throughout the monument.
Even the modern Modoc people don't know who they
were or what their symbols mean.

Early Explorer
Names the Caves
In the 1920's a local miller named J. D. Howard
spent his spare time finding, exploring, and naming
caves. He gave them evocative names like The
Catacombs, Crystal Ice, Skull, and Golden Dome.
Today over 430 caves are known at Lava Beds. Each
is special and contains features found nowhere
else, and their resources are waiting
documentation. The Depression-era Civilian
Conservation Corps worked to create public access
to some of the caves and establish this park. Now
at the start of the 21st Century, numerous
volunteer investigators are generating the
information and knowledge needed to assure its
preservation and continued access.
