Yosemite's dominant rock is granite, a plutonic igneous rock. Magma that cools and solidifies within the Earth's crust forms "plutonic rock", named for Pluto the Roman god of the underworld. The slow cooling of plutonic magma fosters the growth of individual crystals visible to the naked eye. The main minerals are quartz and feldspar.
Darker granite inclusions - "diorite" is mostly plagioclase and other dark minerals, with little quartz and feldspar.
On the east side of El Capitan is the famous diorite dike in darker colors resembling a map of the North American continent, as seen in my photo.

A very well done exhibition of the grandeur of El Capitán! You have handled two things here that always challenge (and usually defeat!) me -- first, there is the problem of conveying the immensity of a subject like El Cap, which you help by showing us the stream in the FG. Second, I often fail in showing the contrasts and relief in a large wall like this; here, those contrasts and relief are the main subjects of interest, from the "North America" diorite to all the other lines and indentations.
