Archeological discoveries in Peru appear to be pretty common nowadays. That or they’re getting more publicity. Including your post, there have several recent finds around Machu Picchu. One in the face of a cliff in “plain sight”.
Check out www.peruthisweek.com , they appear to stay on top of such news...plus more.
