jetty

“I just had a surfer run up to the truck,” a lifeguard said on dispatch audio, “he’s saying there’s a dog that’s on the jetty.”

“Sneaker waves can unexpectedly run significantly farther up the beach than normal, including over rocks and jetties,” the weather service advised.

Robert Smithson had bulldozed dirt and rocks to build a spiral jetty coiling out into Utah’s Great Salt Lake.

Kevin King, 57, was under the influence of alcohol when he crashed his boat — the 48-foot-long “Four Kings” — into the jetty, prosecutors alleged Wednesday.

"Stay off jetties, piers, and other waterside infrastructure," the National Weather Service warned in a release on Thursday.
