Geo 365: Feb. 25, Day 56: Approaching Table Rock

Here, we've come down off Picture Rock Pass (named because there are some petroglyphs on the backside of a large boulder west of the highway at the pass), and we're facing roughly northwest. Table Rock, a tuff ring like the more famous state park Fort Rock, sits on the horizon. While it has much in common with Fort Rock, Table Rock is much larger, and in later stages changed from explosive phreatic eruptions to more effusive basalt eruption. This filled the center of the ring, creating the flat, table-like summit visible here.
