As you can see Colorado Potterers are proud of their high altitude. I've
done some digging and it looks like the highest altitude sailable (within
reason) lake in Colorado and perhaps North America is Jefferson Lake in Park
County, Colorado. It is at 10,687 feet, has a boat ramp and is 145 surface
acres. Ironically it is located in the valley region known as South Park.
Additionally it has a hunting seasons for PWC's and there is a 2 bag limit.
Does anyone know of a higher lake with a launch ramp in North America that
can be sailed? I'm beginning to smell some record setting fervor. Maybe we
can set off some of those self inflating life jackets and have our own
Macy's Day Parade.
