The Jefferson Creek lava flow traveled 13 km down Jefferson and Candle Creeks from an unnamed cinder cone NE of Forked Butte and is younger than the nearby 6,500-year-old Forked Butte lava flow. The two flows traveled down different drainages and joined near this point. The snow-covered summit of Mount Jefferson is visible above the trees.
