I paid a quick 2-hour visit to this area while driving north on US97. My visit was to the Paulina Lake area on the southeast end of the monument, and I hiked most of the trail up to Paulina Peak. I started to visit the beautiful lake, but the black flies were horrible down near the water.
A view from the Paulina Peak trail. Not sure if this is Paulina Peak, Newberry Crater, or neither.

The tongue of a lava flow.
