Standing 602 feet tall and multiple football fields
wide, it is the highest spillway dam in the United States and
one of the largest concrete structures ever built, containing
6.3 million cubic yards of the stuff. The outlook house near the
dam offers films and displays showing highlights of dam construction
during the 1940s.
The second arm is the Pit River arm, the lake's
longest arm which stretches nearly 30 miles.
Since there are lots of dead trees in this part
of the lake, it makes the upper Pit hazardous for boating and
waterskiing. However, the lower part of the Pit is a wide basin
with grand vistas. High above the water is Pit River Bridge, the
highest double-decker bridge in the United States.
To the east is Upper Pit. Known as Shasta Lake's "outback,"
this area is the most remote and offers no services, but does
have three primitive boat access only campgrounds. This area is
considered by many anglers to have the best bass fishing on the
lake.
Unlike Pit, the McCloud arm of Lake Shasta is
home to nine campgrounds, three boat ramps, four privately owned
marinas, two watchable wildlife areas, eight scenic trails, and
a day use area at Bailey's Cove. It is also the stop off point
for Shasta Caverns. The Caverns are open to the public with guided
tours every hour on the hour between 9:00AM and 4:00PM and private
boats can join the tour on the east shore where the ferry ties
up.
Here huge gray rocks formed thousands of years
ago from ocean sediments, extend out above the waterway, creating
deep fissures , crevices and caves.
A self guided trail leads up to Samwel Cave, also
known as the "Cave of the Lost Maiden," from McCloud
Bridge Campground. The cave, believed to contain magic pools in
which the Wintu Shaman would bathe, has yielded Ice Age fossils
found at the bottom of a 70-foot deep pit inside the cave.
All but the first room is closed to the public
because of the danger of falling to the bottom , but experienced
spelunkers can explore the inner reaches of the cave by obtaining
a special permit issued by the Shasta Lake Visitor Center.
