Would anyone choose to use an unusual color aggregate in a bunker that wasn't indigenous to the site?  If so, why?

Does the use of a non-neutral colored sand cause problems around greens?
The USGA doesn't say much about it.

Black sand at Old Works (copper mining slag):


Red sand at Aspen Lakes (Volcanic ash or red sandstone?):


Anyone ever used crushed Guinness bottles for bunkers?

I’ve played from recycled glass from these people

Unfortunately there’s no photo’s. This is a great mom & pop operation and they won’t mind me saying they wouldn’t be using it if it didn’t offer “value for Money”.  Very playable and offers excellent drainage.

A huge number of golf courses do this! ANGC imports white sand for use in their native red clay soil area. I suspect they have influenced a lot of courses to do the same.

I prefer courses use the locally available materials if there are some. The black slag goes well with Old Works IMO.

It seems that extremely white bunker sand, perhaps unfortunately, is not an unusual use.  It can increase sunglasses sales at the pro shop though.  Has anyone successfully used a purple or yellow?  Didn't a PGA tournament use red, white and blue bunkers for independence day once?

Joe Perches,

Due Process had some wonderful ochre sand that blended beautifully with the tall fescue.

Sadly, they replaced it with briiliant white sand that assaulted the eye.

Not a matter of colour but of texture.

I will never forget stepping into a bunker on Gullane #1 only to find that I (and my Titleist) were standing amidst crushed sea shells. Very light and a lot of fun.

As for colour, why would anyone who lurks on this site ever want any colour that did not have a natural look?

Hawktree in ND has the same Black Sand bunker look as Old Works.  As I recall it is a byproduct of the local power plant as well so a playable surface, something different, and it helps with a purpose for what would otherwise be a waste product as well.   I think it works very well there.

Oh, the humanity . Normally we see waste sand from the local mines tightened up a little to make golf course sand; but no adjustments made to color or specification for any course in particular. They're normally too busy making C33 (concrete) sand for their own use. Hence the local color/local course theory.

The bunker sand used at a few of the oft-mentioned courses on the 17 mile drive...is actually a waste product of the local lime quarry in Salinas (one of very few in CA). It is incredibly white....and then "darkened" by the minesite. The specification and color are dictated by the courses, which pay a major premium. Salinas GCC, adjacent to the mine, uses something cheaper (anyone who's played it recently please comment if that is inaccurate).

Of course a recent change to "fluffier" increased our sales to the mine.....and my semi-buried lies @ PB .
