Broghil is a relatively low pass. It was closed for about three months each winter because of snow, but for much of the rest of the year it was passable even for cart traffic.
According to the National GeographicGenographic Project, Broghol Pass appears to be the route used by the ancestors of all modern WesternEuropeans to reach Europe. Modern Europeans carrying the M45 genetic marker crossed Broghol and then turned west; M45 further mutated to become M173 and then M343, which is carried by 70% of the population of England.[1]
