THE CACHE IS NOT AT THE LISTED COORDINATES.
The inspiration for this set of puzzles came from my attempts to solve the nearby But is it Art??. Any resemblance is therefore entirely deliberate ... and probably misleading.
Solve the puzzle to enjoy a walk and some pleasant views in the Essex countryside. You are looking for a micro, so bring your own writing implement.
Congratulations to Mr Crow and gillywig for the FTF.
Tenochtitlan was an Aztec altepetl (city-state) located on an island in Lake Texcoco, in the Valley of Mexico. Founded in 1325, it became the capital of the expanding Mexican Empire in the 15th century, until captured by the Spanish in 1521. At its peak, it was the largest city in the Pre-Columbian Americas.
