On this day 100 years ago, Jack London, then America's most acclaimed author/adventurer, and his wife, Charmian, contemplated the big move.

After two years of construction on the couple's Beauty Ranch in Glen Ellen and the spending of about $80,000 — a million or more in today's dollars — the gorgeous, 26-room, redwood-and-stone Wolf House was nearly completed.

But late the night of Aug. 22, 1913, Wolf House burned.

London, then 37, vowed to rebuild. But he died three years later without having begun the daunting and costly task.

Today the ruins stand as the imposing, heartbreaking centerpiece of Jack London State Historical Park, one of Sonoma County's greatest treasures.

So what, or who, sparked the great fire a century ago?

The spontaneous combustion of rags soaked in turpentine and linseed oil and carelessly heaped by workmen is the generally accepted cause. Jonah Raskin and Gaye LeBaron will offer their perspective on more insidious possibilities Thursday at the Sonoma County Museum.

"To say that the rags in Wolf House caught fire and burned the place down is a cop-out," said Raskin, the author-sleuth and SSU professor emeritus.

In his 7 p.m. talk, he'll share his research into the likelihood the blaze was intentional. Gaye, widely admired for her PD columns and books on local history, will introduce him and offer her own insights.

Raskin vowed the two of them "will open the eyes of even those who insist on keeping them shut tight and not looking at the truths of the matter.

"We've got more than the usual suspects."

SHE WAS DANA ADAMS when she studied at Santa Rosa High in the late 1980s and graduated in 1990.

Today she's Dana Williamson, freshly appointed by Jerry Brown as his cabinet secretary.

Previously the governor's senior advisor, Williamson, 41, now has even more power in the capitol. To get the former Panther's attention should you email her with suggestions for vitalizing California, jot in the subject line, "Bleeding Orange and Black."

FORE WOMEN: One thing missing at Santa Rosa Junior College is a women's golf team. But that omission is about to be remedied.

Coach Derek Felciano, the pro at Bennett Valley Golf Course, holds the first practice Tuesday for SRJC's new women's golf club. Though not a school team, it will be eligible to compete in the Big 8 Conference.

Students interested in joining the team, to be advised by men's golf coach Dave Herrington, should putt a note to srjcwomensgolfclub@yahoo.com.

STAYIN' ALIVE: There's a good reason the classic Bee Gees disco tune was the sound track to a special all-school assembly Friday at Cardinal Newman High.

It was a lifesaving class — with more than 600 students present, the largest cardio-pulmonary resuscitation class the local American Heart Association chapter has ever taught at a school.

The instigator: sophomore Colby Groom. He's the amazing teen who survived two open-heart surgeries and works to help other kids avoid the trauma by raising serious money — more than $1 million, easily — for research into preventing heart defects.

A good chunk of the cash Colby has come from sales of the wine, Colby Red, created by his winemaker dad, Daryl Groom. At the CN assembly, Colby told his tale and urged his schoolmates to join him for the Sept. 8 North Bay Heart Walk at Howarth Park.

Then paramedic and /disc jockey Ted Williams and some Central Fire Authority firefighters demonstrated the proper technique for administering chest compressions to someone who's stopped breathing.

Williams piped in "Stayin' Alive" as students practiced, not only for the appropriate lyrics. The song has about 100 beats per minute, just right for timing chest compressions.

Try it.

Stayin' Alive.

Stayin' Alive.
