Newberry Volcano is the largest volcano in Oregon, a broad shield volcano with a huge area of 600
square miles (1500 square km) and massive volume of 110 cubic miles (450 cubic km) which are second only to
Medicine Lake Volcano in the entire Cascade Range. These two volcanoes are near twins, with similar size,
elevation, structure, evolution, and volcanic products. Both are located in the high desert, well east of the
Cascade Crest, and thus receive somewhat lower snowfall than the main range to the west. The summit of Newberry has
collapsed to form a large 3 x 4.5 mile (5 x 7 km) caldera known as Newberry Crater, which holds two lakes, Paulina
and East Lakes, that contain a number of hot springs revealing that magma lies close below the surface. Several
large and easily accessible obsidian flows cover large portions of the caldera floor, while the flanks of the
shield are studded with over 200 cinder cones. The numerous lava flows originating from these cinder cones contain
dozens of known lava-tube caves, including several whose depths hold permanent ice throughout the year.
Despite these similarities to Medicine Lake, there are a number of important differences which make
Newberry a better ski objective. The highest point on Newberry is Paulina Peak, a massive extruded dome which has
a gravel road to its summit. The northern side of Paulina Peak is steep, with a number of gullies offering
excellent (albeit somewhat short) downhill runs. Newberry is also much more developed, since it was declared a
National Volcanic Monument in 1990. The main access road is excellent and paved, and it is plowed in winter to
access two snowparks, the closest of which is only 2 miles from the caldera rim. In spring, the remaining segment
of the road into the two lakes is also plowed open, allowing very short access to a variety of nice ski routes,
most of which are more cross-country than downhill. Unfortunately, despite its semi-protected status as a National
Monument, all of Newberry is open to snowmobilers, and they usually outnumber the skiers in both winter and spring.

This easy but circuitous route ascends the snow-covered road to the summit
of Paulina Peak, following a gentle 10% grade as it winds and switchbacks uphill. In
winter, a nordic ski trail parallels the unplowed road from the last snowpark into the
caldera, adding several miles to the trip. The main reason for doing this route is the
astonishing view from the summit. The entire length of the Oregon Cascades fills the
western horizon, from Mount Hood all the way south to Mount Shasta in California. To the
south lie hundreds of cinder cones dotting the southern flanks of Newberry itself, while
to the north and east is the broad expanse of Newberry Crater with its two lakes, several
obsidian flows, and Central Pumice Cone.

Descending the summit road may satisfy cross-country skiers, but most
ski mountaineers will look for something more interesting. The two best options are
to ski down the northeast or northwest sides of Paulina Peak. The northeast is a broad,
steep bowl which drops directly from the summit down towards the toe of the Big Obsidian
Flow, while the northwest side is series of steep, narrow chutes which drop through lava
ridges and pinnacles in a bowl beginning several hundred yards northwest of the summit.

North Paulina Peak is much less prominent and far less visited than
Paulina Peak, a mere bump which is the highest point on the northern rim of the
caldera. A trail leads along the rim from the Paulina Lake entrance, although this is a
snowmobile route in winter. Instead of returning along the trail, a more interesting
descent route heads due south down the sloping caldera wall to reach the Interlake
Obsidian Flow, which completely spans the saddle between the two lakes. After crossing the
flow, it is a simple ascent to reach the summit of the Central Pumice Cone, a large cinder
cone towering over 700 ft above the center of the caldera. A short but steep descent
followed by a long traverse around Paulina Lake leads back to the trailhead.
