Three distinct basalt flows below Bogus Rim?

This first photo is looking west into a basalt-choked tributary valley just downstream from Iron Point. I recall inferring three major intracanyon flow units here divided by conspicuous breaks. Just throwing it out there for all to consider.

This photo is looking upstream from west side of the river (near Rinehart Mesa) toward and beyond Jackson Hole. The intracanyon flow sequence here is very thick. Possibly three units here as well? The lower shelf right above the talus slope has the 'hackly' texture that we see at the base of the section near Rinehart Creek as well.
