This collection consists of seven leather bound portfolios containing topographical drawings, maps, floor plans, notes and papers that the West brothers had created when working in the Maharashtra region of India in the mid to late 1800's. The main focus of the collection is the Kanheri Caves; a group of over 109 rock cut temples located in what is today the Sanjay Gandhi National Park on the western outskirts of Mumbai. The brothers studied these caves over the course of several decades, returning to the site many times to check and amend measurements, locations, and expand open their interpretation of the site. The remainder of the collection covers several other sites such as: Ajanta, Ellora and Daulatabad.

The portfolio contains three folders. These are titled: 'Ajanta Caves 1', 'Ajanta Caves 2', and 'Ellora Caves and Aurangabad Caves'.
