Mylonitic Quartzite

Yesterday started out cold and icy - with an orangey sunrise over the nearby mountains to the east. Later, the sun came out and everything around started melting and dripping.

If you look closely, you can see a fold or monocline concealed partly by snow. Folded limestone atop a reddish limestone breccia sits on Precambrian to Cambrian, possibly mylonitic quartzite. And speaking of mylonites (once again), it turns out that mylonitic quartzite was rock of the week at All of My Faults Are Stress Related. What a coincidence!
