Pic One is the Horn Creek Drainage, probably 1/2 mile NE of the campsite. I can't quite place pic 2. Scratch, if you went to Plateau Point from the Bright Angel you could look west towards this area. It's a few miles west from Indian Garden on my favorite trail, the one and only Tonto. I just love traversing that canyon on that platform. It's the next drainage west where you really need to watch your feet in places. The Inferno made me sweat, worrying how my wife would handle the slanted exposed trail, She went through it just fine. Trekking poles. Godsends.
WD could walk backwards, blindfolded through it; we're mere old mortals.
