This is part of the same enormous lava flow we saw at stops 6 and 11. Recent work makes a good case that the Lovejoy is an early member of the great Columbia River Basalt group, extending it much farther to the south and west than suspected before. The origin of the Lovejoy is a few kilometers east of here. This locality, like stops 18 and 19, is beyond the crest of the Sierra Nevada, but at the time it was erupted there was no barrier between here and the Pacific coast.
