Neil_Crafter:
Here is the 1926 plan for Cypress Point, as drawn up by San Francisco artist Albert Darrows, based upon a sketch that Mackenzie provided him with. I expect the plan came out of Mackenzie's first visit to the US and to Cypress in Jan to March 1926.
How it differs from Raynor's plan is very hard to say, but as Hollins was there with both of them, its fair to say she had her influence, so some holes would be routed the same. And the final on the ground routing differed from this routing too.
As for 16, here's an enlargement showing the hole as Mackenzie first sketched it. Please note the rear tee that is shown giving the dotted alternative line of play as a two shot hole. The card on this plan shows the hole as a 200 yarder, so perhaps when Hollins made her shot it was not as long a carry from the rear tee today. From what I have read, Mackenzie was not all that confident about the hole as a par three, and in an early article on the course, published in The Fairway magazine in November 1928 (and Golf Illustrated UK) he lists the hole with a championship length of 350 yards, compared to the regular length of 240 yards. Geoff S in his book suggests that Mac was keeping his options open, and if play as a long par 3 was too problematic he would then lengthen the hole to a two shotter by building that championship tee so that the hole could play at 350 - presumably there was enough space between 15 and 16 to allow for that.
So, Mac's first iteration for 16 was a shorter hole, some 40 yards shorter in fact. And Hollins shot across the chasm may well have been played from ahead of where the current back tee sits, making the carry less that 200 yards.
Neil, do you still have these?
