Depending on the gravel, there's a decent chance you can tear a sidewall in those tires. Unless, the gravel is really jagged, I'd go for it, but carry a boot, and a spare tire.
The Rolfs should be fine. We've ridden double track with Rolfs, and 25mm tires.
You could fall off a cliff and die.
You could get lost and die.
You could hit a tree and die.
OR YOU COULD STAY HOME AND FALL OFF THE COUCH AND DIE.
