Just before Chincana is a large rock called Titi Khar’ka.  On the left side of Titi Khar’ka is a rock formation nicknamed the Face of Viracocha.  On the right side are indentations in the rock nicknamed the Refuge of the Sun and the Refuge of the Moon.  I also saw a square notched area in the rock, although I do not know what it is about.  I did not really feel anything at this rock.  Just my experience at that point in time.  Maybe I need to return and experience this rock again as well...
