Congratulations on completing the Essex Tiny Doors Adventure Lab # 2. This five stage adventure shows off the craftsmanship of a local cacher, Yetiatlarge, who is an Essex resident.
This cache is not at the posted coordinates but is within 1 km. You will need to visit all five of the lab stages in order to reveal the missing letters that form the coordinates of the bonus cache's location: N 42 10.ABC W 82 49.DEF
