Johann Jakob von Tschudi, Travels in Peru, on the Coast, in the Sierra…
“ The Montaña of San Carlos de Vitoc is, without exception, one of the most interesting districts of Peru. It has on the one side, and at a short distance, the populous villages of the Sierra, and on the other it borders on the forests, through which the wild Indians range in their hunting excursions. It was formerly the principal key to the missionary stations of the Pampa del Sacramento, the Chanchamayo, Perenc, and Upper Ucayali. It is only twenty leagues distant from Tarma, from whence the road leads through the fertile valley Acobamba, to Palca. ”
