The architectural evolution of East Lake #1 is a puzzle. George Adair re-routed the old Bendelow course (see Am. Golfer Nov. and Dec., 1912). The Adair routing is, essentially, the current routing. The only evidence of specific work by Ross was his addition of some bunkers in 1914 or so. Yet Ross claims East Lake #1 as a remodel.
My guess is that East Lake was happy to have Ross claim the course. But based on what we can confirm about what he did there, the claim is a bit thin. (BTW, there is nothing in the Tufts Archive connecting Ross and EL #1.)
Adding to the puzzle is that Ross did the same work at the same time a few miles away at Druid Hills, but did not list Druid Hills as one of his remodels.
