EVERY COMPANY GUIDE I asked had only good things to say about Silitch. He is sympa, says Eric Mathieu, meaning "friendly." He's a bon guide, says Daniel Simond. He's a très bon professionnel, says Lionel Pernollet.

Still, while no one would ever say such a thing outright, odds are that some guides probably wonder about Silitch's qualifications, simply because he's American. While places like France, Italy, Switzerland, and Canada long ago adopted a stringent curriculum that all aspiring guides had to complete before being allowed to work, for many years in the U.S. you could become a guide simply by working for a company that said you were a guide. It wasn't until 1997 that the Boulder, Colorado–based American Mountain Guides Association created guiding schools acceptable to the International Federation of Mountain Guides Associations, the Switzerland-based body that oversees worldwide accrediting.

"A friend of mine heard a guide talk about an American once as a ‘candy' guide," says Kathy Cosley, "like he wasn't the real deal."

Silitch spent years working and passing international tests in ice climbing, alpine climbing, and ski mountaineering, mostly in the Pacific Northwest. Now that he's internationally certified, he can guide independently in more than 20 countries, including France. This irks other French guides, who can't guide independently on, say, Denali, because they'd need a permit from the National Park Service. Those permits are already locked up by six authorized concessionaires.

Silitch will never be French, of course, but his background has prepared him to fit in, as both a guide and an expat. The son of a folk-artist mother and an engineer father, he began learning French in kindergarten at a private school in Annapolis, Maryland, where he grew up. When he was five, his parents divorced and he stayed with his mother, Natalie. She bought a white VW van and took him and his two younger sisters camping on road trips to Florida, Canada, and Oregon.

"There I was in the sixth grade having to read the maps, light the camp stove, and set up the tents," Silitch tells me over crab cakes at Munchie, a Swedish restaurant off the Rue des Moulins. "I never thought about it, but I guess that was my first time acting like a guide."

Silitch was a quick learner, but he did only so-so in school. His mother decided he needed a masculine influence in his life, so in ninth grade he was sent to Purcellville, Virginia, to live with his dad. Peter Silitch had remarried an Austrian countess, Elizabeth Colloredo-Mansfeld, and she got her stepson to buckle down by rewarding him with wine if he finished his homework before dinner. Today, Silitch drinks so infrequently that even a digestif will make him gag, but her methods worked. He got straight A's, earned the highest score in the state on a standardized French exam, and won a scholarship to a private boarding academy in New Hampshire called Holderness School.

Holderness sits near the Rumney cliffs, and Silitch dove into rock climbing. Soon he and Kevin Dippy, a housemate, were roping up every chance they got. "Kevin and I would sneak off to Cannon Cliff or ride our bikes out to radio towers that we could climb and rap off," Silitch says. "We planned to take a year off to go to France to pick grapes and climb, but then Kevin died."

Silitch isn't chatty to begin with, and here he trails off. He typically slots words into sentences with the precision of a climber plugging protection into a crack. Talking about his friend seems to gunk everything up, so he retreats. He'll add only that Dippy and a partner had been climbing near Telluride, Colorado, when an anchor failed. Both of them died.

After Dippy's death, Silitch headed into the blank pages of the American West. He skied big lines in North Cascades National Park and bagged Mount Baker, South Early Winters Spire, and Monte Cristo Peak. In 1980 he was in a couloir in the Enchantments when Mount St. Helens erupted and covered his car in ash.

Silitch graduated from St. John's College, in Santa Fe, New Mexico, in 1986. After several years of bouncing around—working for Outward Bound in the West and taking a sports marketing job with Nestlé back east—in 1994 he signed on with the American Alpine Institute (AAI), in Bellingham, Washington. He led doctors and lawyers up routes in Canada, South America, and Alaska. He started to think: He could either keep guiding those guys (and make $120 a day) or become a doctor himself and work on Denali. A few years later, he signed up for premed classes at the University of Colorado in Boulder and aced the coursework with a 3.9 GPA.

He never went to med school, though. One day at his condo, he looked at a copy of Holderness School Today, his alumni magazine. He saw a short announcement from Nina Cook, a native of Maine and a Holderness grad who'd moved to Boulder to teach. "It said something like ‘I'm new to town,' and it listed her phone number," he says. He called and offered to make her pancakes.

"Sure, it was a little weird," Nina says. "But he had real maple syrup."

The two hit it off, climbing and running and skiing together. "Then Michael starts talking about going off to Antarctica or to med school in Des Moines," Nina says. "No way was I going to Des Moines."

One day, the phone rang with a job offer from the AAI to spend a summer guiding in France. Michael turned to Nina and said, "What about Chamonix?"
