Belknap Shield Volcano and Points of Interest
Belknap Shield Volcano
-- Geographic Setting, Geologic and Eruptive History
Belknap Crater is the focal point of a long-continued and complex episode of
Holocene basalt and basaltic andesite volcanism.
The broad shield is 5 miles in diameter;
it is estimated to be 1,700 feet in maximum thickness and 1.3 cubic miles in volume.
The volcano probably contains a core of cinders which interfingers with peripheral
lavas and whose surface expression is the summit cone. Basaltic andesite
issued from vents at the north and south bases of the cone approximately
1,500 years ago.

Dee Wright Observatory
The Dee Wright Observatory is a stone memorial to the famed architect Dee Wright.
It is located in the
middle of a massive lava flow and offers panoramic views of the
Cascade Mountain Range, as far north as
Mount Hood. A barrier free access trail takes visitors to an
interpretive court, offering information on the
history of the structure built in the 1930s by the
Civilian Conservation Corp. At the top of the observatory, a
bronze peak finder points to geologic features
amidst sweeping lava fields. The half-mile Lava River
Interpretive Trail takes visitors on a
30-minute walk on a paved surface through lava flows with spectacular
vistas of the surrounding landscape.
