The Thames Valley Trail stretches for 110 km from its southern terminus on Southdel Drive at the Elgin Trail north terminus, to its northern terminus in St. Marys at the Avon Trail west terminus. This series of caches follows the off-road trail portions of the Thames Valley Trail (TVT) and are named for various fictional characters of the Star Trek universe.
Lieutenant José Tyler was the helmsman of the starship Enterprise during the pilot of the series, under Capt. Christopher Pike.
The cache is a micro on a tree in the hedgerow between the fields, along the trail.
