Those are really nice pictures... my trip to Peru was for business about 16 years ago... never got to go up to Machu Picchu but did get to visit a museum that had a bunch of artifacts from there. They were very impressive.
I spent 2 or 3 days in Lima visiting a client, then flew up to Carjamarca to visit a gold mine that was being worked... they were strip mining a 14,000 foot mountain... being a flatlander from Houston which is below sea level and suddenly finding my self at 14,000 feet I had some serious breathing problems, expecially when I saw locals swing sledge hammers driving stakes... I get winded at 900 feet in TN using a 3 lb sledge to put down rebar in my landscape timbers... they wound up giving me a cup of coca tea to help with the breathing.
Carjamarca is the town where the Spaniards captured the Inca king and demanded a room filled with gold as ransom... the town is at only 10,000 feet.
