Highpointing is the sport of ascending to the point with the highest elevation within a given area.
The Highpointers Club promotes climbing to the highest point in each of the 50 U.S. States.
Alaska’s Denali is the most difficult. The lowest is 350′ — Florida’s Britton Hill. About 20 of the states can be ascended by automobile. Only 10 to 20 require serious effort.
