WOODY CREEK, Colo. - With a deafening boom, the ashes of Hunter S. Thompson were blown into the sky amid fireworks late Saturday as relatives and a star-studded crowd bid an irreverent farewell to the founder of "gonzo journalism".

As the ashes erupted from a tower, red, white, blue and green fireworks lit up the sky over Thompson's home near Aspen.

"I'll always remember where I was when Hunter was blown into the heavens," said Thompson's neighbor, Rita Sherman, who watched the spectacle from the deck of her house.

The 15-story tower was modeled after Thompson's logo: a clenched fist, made symmetrical with two thumbs, rising from the hilt of a dagger. It was built between his home and a tree-covered canyon wall, not far from a tent filled with merrymakers.

"He loved explosions," explained his wife, Anita Thompson.

The private celebration included actors Bill Murray and Johnny Depp, rock bands, blowup dolls and plenty of liquor to honor Thompson, who killed himself six months ago at the age of 67.

Security guards kept reporters and the public away from the compound as the 250 invited guests arrived, but Thompson's fans scouted the surrounding hills for the best view of the celebration.

"We just threw a gallon of Wild Turkey in the back and headed west," said Kevin Coy of Chester, W.Va., who drove more than 1,500 miles with a friend in hopes of seeing the celebration. "We came to pay our respects."

Thompson fatally shot himself in his kitchen Feb. 20, apparently despondent over his declining health. The memorial, however, was planned as a party, with readings and scheduled performances by both Lyle Lovett and the Nitty Gritty Dirt Band.

The author's longtime illustrator, Ralph Steadman, and actor Sean Penn were on the invitation list, along with Depp, who portrayed Thompson in the 1998 movie version of "Fear and Loathing in Las Vegas: A Savage Journey to the Heart of the American Dream," perhaps the writer's best-known work.
