Tuesday, July 14
Beautiful day! You can see forever, or at least to the horizon.
Monhegan Island is clearly visible (22.5 miles), Portland (24 miles) and Mount Washington (height of 6,288 feet) in New Hampshire (86.3 miles). Visibility today is only limited to the curvature of the earth.
A person of average height standing at sea level can only see 2.8 miles out to sea. With an increase in height this number changes dramatically. There is a mathematic formula for figuring this out:
Remember the Pythagorean Theorem?



a2 = 39632 + x2 = 15705369 + x2
Solving for x,
x2 = a2 - 15705369
a must be 3963 miles + 6 feet (Let's say the men are actually 6'3", so their eyes are six feet above ground.). Thus
a = 3963.001136 miles
x2 = 15705378 - 15705369 = 9
x = 3 miles
but for my purpose let’s just say that today we could see “forever”.
I returned to the South trail to finish mowing. It is now looking good. Brenda weeded the garden and it is looking good. Don’t know if we will get any tomatoes from our lone tomato plant but the flowers look good. At least the rain didn’t drown everything!
After lunch I trimmed the Lighthouse trail and Brenda hosted a handful of guests at the lighthouse. One visitor was from Moscow and another from Finland. Sure do get people from all over the world.
Tomorrow we go ashore. We have an appointment with a reporter for a news article about caretaking and our adventures on Seguin. I’ll let you know how that goes.
