The list above doesn't quite tell the whole story of Maxwell's work at ANGC. Here is a more comprehensive listing of what we know about:
1 – Filled in the bunker on the left side. [1937]
3 – Removed the front tongue on the green and reshaped the bunkers. [1937]
4 – Rebuilt the green diminishing its pitch, turning it closer to the 90 degree configuration of today, widening the left tongue and pushing the bunkers closer to the collar. [1938]
5 – Removed the artificial sand dunes. [1937] Reshaped the green to create ocean-wave contours. [1937]
6 – Rebuilt the green removing the mound, leaving the left side redan features and adding a prominent right side shelf. [1937]
7 – Removed the artificial sand dunes. [1937] Reshaped portions of the green per Clifford Roberts’ request. [1937] Built a new postage stamp green with three bunkers in front beyond the original green. [1938]
9 – Redesigned and rebunkered the green. [1938] Added back a portion of the tongue on the front of the green. [1938] Flattened the tongue on the green. [1939]
10 – Removed the artificial sand dunes. [1937] Built a new green up the hill and to the left of the original green. [1937]
12 – Enlarged the right side of the green and added the back bunkers. [1938]
14 – Merged a lower deck on the putting surface and added rightside fairway knobs. [1939][
15 – Lengthened the hole. [1940]
16 – Expanded the green to the left and pulled the two bunkers closer to the green. [1937]
17 – Remodeled the green and added three bunkers at the front changing the character from a run up hole to a pitch to the green. [1937] Removed the artificial sand dunes. [1937]
18 – Eliminated the long front tongue. [ 1937] Reshaped the green. [1938]
General – Removed the piles of dirt that were added to look like sand dunes. [1938] Made other minor changes. [1940] Moved tees and greens on five holes (unclear if this was a reference to new work or work done since 1937). [1941]
