Chill an Old Fashioned glass by filling it with ice water and set aside.

In a mixing glass, combine the bourbon, sweet vermouth, dry vermouth, and apricot liqueur.

Add ice to the mixing glass and stir until well-chilled.

Empty the ice water from the Old Fashioned glass, then add a large ice rock.

Strain the mixed cocktail over the large ice rock in the Old Fashioned glass.

Garnish with a slice of orange before serving.
