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.
Dr. Katherine Pulaski was the interim Chief Medical Officer on the Enterprise when Dr. Crusher served on Starfleet Medical.
The cache is a micro at a height between ankles and knees.
