I just made the Grand Canyon Supergroup article, and linked it in the Cardenas Lava article. Here are some important notes / observations. (the Cardenas Lava is one of first articles, and needs adjustments)
The reds of the Dox Formation are on the northeast bank of Basalt Creek (confer with a photo from Hiking Arizona's Geology, Hike 3, Tanner Trail. (by Ivo Lucchitta)). The photo (above, or other photos), and a graphic interpretation of the photo shows some interesting items (in book: photo left, graphic of photo, right).
The thick, grayish banding-(sub-unit), above the red bandings of the Dox Formation is clearly like the Cardenas Lava layers above it. One can notice the organized, colored, multi-banding in the photo is the Nankoweap Formatiion, above the Cardenas Lava, and in contact with the underside of the Tapeats Sandstone-(in other photos, for example at Apollo Temple, downstream), short cliffs ( cliff-former). The Tanner Graben (a down-dropped graben) is why they appear in the same photo; the Nankoweap is on the top of the graben.
So... because I have recently only created some of these geology unit articles, and putting photos in the categories in WikiCommons, I want to suggest that it appears like some interbedding of the top of the Dox Formation with the lower "Cardenas Lavas" subunits. Most of the photo in Lucchitta's chapter, Tanner Trail, shows the Cardenas as "slopes", as is the Dox Formation. The exception is the photo from Comanche point (in Article) which also seems to show Tapeats Sandstone cliffs-(the bottom of which is the Great Unconformity). It seems like there are only some sections of the Cardenas Lava that are "resistant", 'island' sections (like Lava Butte). (from the HOT SonoranDesert, ArizonaUSAl...
