Newberry Crater was formed by the eruption of what was one of the largest and most active volcanoes in Oregon. Successive flows cover 500 square miles. As with Crater Lake, the summit of the volcano collapsed after a large eruption, creating a caldera.
Initially a single body of water, Paulina Lake and East Lake are now separated by a lava flow and a pumice cone. Due to the lakes' great depths and the constant flow of fresh mineral spring water, stocked trout thrive here. Looming above is 7985ft Paulina Peak .
A short trail halfway between the two lakes leads to the Big Obsidian Flow , an enormous deposit on the south flank of Newberry Crater. The Newberry Crater Rim Loop Trail encircles Paulina Lake and is a good place for hiking and mountain biking.
To get there from US 97, take Paulina East Lake Rd to Newberry Caldera.
