A. Bandelier

A. Bandelier was credited in Indiana Jones' journal for sketching the map to the Temple of the Chachapoyan Warriors in 1893.

Behind the scenes
The Lost Journal of Indiana Jones stating that Bandelier drew the map to the Temple of the Chachapoyan Warriors creates a continuity error with the Raiders of the Lost Ark Sourcebook which attributes the map to an explorer named McHenry.
