The deepest bunker in golf is named after a mountain range, and for good reason. It's called the Himalayas or Himalayan bunker, and it's a 40-foot-deep, 25-foot-wide bunker at Royal St. George's, a regular host of the British Open Championship. It sits on the par-4 fourth hole at the Sandwich club and is lined on three side with wood planks to keep it shape.
The deepest bunker in the United States, however, may be on the par-5 16th at PGA West's TPC Stadium Course. It's 19 feet deep, and it comes into play regularly during the PGA Tour's CareerBuilder Challenge in Palm Springs, Calif. The most famous victim of this bunker is former House Speaker Tip O'Neill, who gave up trying to hit out of the bunker one year during the former Bob Hope Classic.
Some other deep bunkers include the Hell bunker on the 14th hole of the Old Course at St. Andrews, which is about 12 feet deep.
There's also the Chambers Basement bunker at 2015 U.S. Open host Chambers Bay in Washington, which is a 10-foot-deep bunker in the middle of the fairway at the par-5 18th hole, just shy of the 100-yard mark.
