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.
T'Pau was a Vulcan leader who presided over the Koon-ut-kal-if-fee ceremony in which Spock was forced to fight Captain Kirk after Spock was rejected by his bride-to-be, T'Pring. She was also the only person ever to turn down a seat on the Federation Council.
The cache is a micro near the Heatly Dr. trailhead.
