Fowler's bunkering at the initial version of LACC North was quite utilitarian. There is a very good aerial in the clubhouse of the 1st hole, Fowler version....with the 9th and 18th green featuring Bell bunkering, taken during the late 20's remodel, (perhaps they did a preview for the members).
Sean Arble; thanks for the excellent photo of the Weston (pre-CA) bunkering. My influence theory is loosely based on Meadow, and some earlier works across the pond. Weston certainly debunks a portion of that. Any idea if Cole or Fleming were involved in the construction of Weston?
I don't have my reference material or timeline handy, but fairly sure that Bell's Castlewood in the East Bay predates Meadow, as does La Cumbre, which had some rather wild bunkering. One has to imagine that Mac-Hunter would have seen these prior to, or during the infamous trip to Riviera during construction, and it might have influenced the evolution of their famous CA bunkers.
If someone has the Bell/Mac timeline, and the interest to post it and compare the two would be beneficial....
