Petroglyphs at Taliesin West.
I was taken on a guided tour of Taliesin West, the winter home of Frank Lloyd Wright and his architecture school, which he started building in 1937 and where he lived (for the winter) till his death. The organic architecture is unassuming and brilliant, using local materials and the interior spaces were genius! I thought the whole thing was fantastic. While Frank and his students were digging up the path for the driveway in Taliesin West, they unearthed beautiful rocks with petroglyphs from the Hohokam tribe. It is one of these symbols on the rocks that inspired Frank Lloyd Wright's logo for Taliesin West.
The family friend who invited me for this tour, then took me for a drink and snack at the Arizona Biltmore, where Frank was the design/architect consultant with Albert Chase McArthur who built it in 1929. It's a stunning building where I got to sample some local ales!
