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.
The Horta was a silicon-based organism on the planet Janus VI which was disturbed by the mining operations and killed a number of miners while attempting to protect its environment, in the Star Trek episode The Devil in the Dark.
The cache is a micro on the branch of a small tree, up high.
