North-facing view of the 4-by-5 mile Newberry Caldera from the top ...

Newberry caldera's two lakes, Paulina Lake (6,331 feet), on the left, and the slightly higher East Lake on the right are fed by snowmelt, precipitation, and hot springs from depth. The 7,084-foot-high Central Pumice Cone sits between the lakes. The mostly treeless Big Obsidian Flow, youngest lava flow on the volcano (1300 years old) lies surrounded by forest south of the lakes. On an especially clear day, the view from Paulina Peak extends north to Mount Adams in Washington State, and south to Mount Shasta in California.
