Geo 1095: March 27, Day 816: Fiery Flow

Continuing over Tombstone Pass, after the site of the most recent posts, we come to McKenzie Junction. I've posted a number of photos from here before, which were also taken on this particular day trip. However, I was just starting the Geo series, and there were quite a number of shots I skipped at the time that I think are worth sharing. In addition, since those earlier posts, I've been back to the McKenzie trough/River/Pass at least three or four times, so I'll be mixing in some shots from those trips as well. You  might like to review the geology of this spectacular area in these posts from the wayback machine:

Geo 365: Jan. 21, Day 21: Reflections
Clear Lake Addendum
Geo 365: Jan. 22, Day 22: Clear Lake Lava
Geo 365: Jan. 23, Day 23: McKenzie Junction and Three Fingered Jack
Geo 365: Jan. 24, Day 24: Close Enough
Geo 365: Jan. 25, Day 25: Sahalie Falls
Geo 365: Jan. 26, Day 26: Koosah Falls
Geo 365: Jan. 27, Day 27: Springing Forth

This is looking north from the highway berm; the slope in the upper mid-left more or less represents the western half-graben of the High Cascades Graben (See "Day 24: Close Enough," above). But what really delights me about this photo is the bright red vine maples, echoing the recent fire of this flow. I'm not sure whether this particular lava flow is from Nash Crater or Little Nash Crater, but it's almost certainly one of those two. There were a number of recent flows from a line of cinder cones east of here about 3000 years ago.
