View upstream at big bend below Iron Point. There is small intracanyon flow remnant visible on strath near river. Hard to make out in this image.
View upstream at big bend. Iron Point on right.
Upper rhyolite pinching on sed which overlies lower rhyolite. Character of sediments suggests major baking by rhyolite. Note slope character beyond the pinch.

Yep. Iron Point. You haven't been?
The Gorge as seen looking north from Iron Point.
View of IP from the Bride of IP
View looking north from the Bride of Iron Point. This is a fin of rhyolite that extends straight (!) up from the river.
View of Bogus Lavas from Bride of IP. There are multiple (at least 2) intracanyon flows preserved in this reach.

How many times will I take this picture?
View north toward AM-PM camp.
How could this not be a landslide?

What is that buzzing sound?
Buzzworm on the rim

View upstream toward Iron Point. Note the two intracanyon flows on right side of photo.
6 meters or more of fluvial gravel on the Bogus Rim lava. Clasts almost entirely rhyolite and basalt.
Incision opportunity seized.
Two intracanyon flows are evident here...note thick palagonite on top of tan-orange volcaniclastics. It forms the base of the lower flow.
Look carefully for two pinch-outs of the intracanyon flow pair here.

How does the paleochannel at the left edge of the photo relate to the topography just beyond the upstream edge of the WC flow?
