Glaciers Of Kenai Fjords:
Instructional Resources
The Instructional Resources used in the
Kenai Fjords activities are organized and presented in two sections.
The first section organizes the Instructional
Resources by resource type. The second section
presents the resources organized by activity number.
At the end of the resources sections is
a glossary of glacier terms used in
the student activities.

arête:
a sharp ridge bounded by steep slopes and found in glaciated areas;
arêtes are formed by two adjacent glaciers
cirque: a
glacially eroded basin shaped like half a bowl; a deep, steep-walled
recess in a mountain, caused by glacial erosion
cirque
glacier: a glacier that sits high on a valley wall and doesn't
reach down to the valley floor; tend to be wide rather than long
crevasse:
a crack in a glacier that is formed when a glacier flows over uneven
ground; the top layer of the glacier cracks under pressure and forms
a crevasse
firn: When snow
compacts it becomes more and more dense; on intense compaction,
snow becomes ice; firn is an in-between stage - too dense
to be called snow, but not dense enough to be ice
firnification:
the process of snow turning to ice through years and years of snowfall
at cool temperatures; this process creates glaciers
fjord: a long,
deep and narrow sea inlet formed by glaciers; as the glaciers retreated,
the sea level rose, filling these U-shaped valleys with seawater;
all of the bays in the Seward and Prince William Sound areas and
Southeast Alaska are glacier-formed
glacier:
an accumulation of ice that moves downslope under the influence
of gravity; formed by the accumulation and compaction of snow
glacier
flour: very finely crushed rock; this fine, powdery dust is
the result of the rocks within the glacier scraping
lateral
moraine: piles of rocks (moraine) that are deposited along the
edges of a glacier; the Mt. Marathon "bench" on the hike to the
Mt. Marathon bowl is a lateral moraine
medial
moraine: a moraine in the middle of a glacier, formed by the
edges of two glaciers that flow together; within Bear Glacier one
can see two medial moraines -- they look like long highways within
the glacier
meltwater:
water within or underneath a glacier created by melted ice or snow
moraine: a
jumbled pile of rocks carried along and deposited by a glacier;
recent moraines and older moraines can be seen on the walk out to
Exit Glacier
nunatak:
a Native Alaskan word that means "lonely peak"; these lonely peaks
are seen peaking up through ice fields
recessional
moraine: moraines left behind by a glacier that is receding
or retreating; a recessional moraine is forming at the tongue or
terminus of Exit Glacier
striations:
lines that have been cut or scratched into rock surfaces over which
a glacier has passed
surging
glacier: glacier that advances rapidly at regular intervals;
surging is the sliding forward of the ice at great rates; some glaciers
in full surge can advance as much as 100 m (333 ft) per day
terminal
moraine: a moraine at the very end of where a glacier has extended;
most of the terminal moraines in the Seward area are underwater
? melting glaciers have raised the sea level and drowned the terminal
moraines
tidewater
glacier: a glacier that flows into the ocean; Aialik glacier
is a tidewater glacier
U-shaped
valley: a valley with a U-shaped profile that has been formed
by a glacier; these valleys have steep valley walls. The grinding
and carving of the glacier forms the U shape. When these valleys
fill with seawater they become fjords
valley
glacier: a glacier that is confined to a valley and restricted
in width by valley walls; Exit Glacier is a valley glacier
