There are two confluences in the state of Connecticut; both are approx 2 miles south of the Massachusetts border.
The location begs the question: were the founders attempting to lay the state boundary exactly on 42N but missed the spot because there was no GPS in the year 1642? The probable historical reconstruction is comical; a team of colonial surveyors, in silk breeches and powdered wigs, standing in a forest, holding sextants, attempting to define a latitude to within a few minutes of arc! It's amazing they got it within 2 miles!
My approach to this confluence was from the south. This area is Old New England; farm lands & 18th century houses. Rolling hills with civil war vintage cemetaries & churches with steeples. Many old farmlands are being reclaimed by hardwood forests.
From recent DCP reports, I knew this confluence was just off state highway 169; in front of a newly constructed house. I brought a copy of the "letter of introduction", and talked at length with a congenial property owner who granted me full access to his yard to find the confluence.
The GPS zeroed out just 6 feet in front of the garage door, as the owner's large malevolent dog barked his disapproval from the nearest window.
I took the requisite photos and left the site. The temperature was 35 F; the skies were clear; there was 2 inches hard packed snow on the ground.
The local flora was typical New England; oaks and pine; with a smattering of maple & beech. Shrubbery was minimal.
Within a mile of the site, herds of deer were seen grazing in the abandoned fields. It was an early Saturday morning & there was little human activity in this sparcely populated area.
