Mayne Reid,
The Lost Mountain: A Tale of Sonora
“ The ascent, commenced almost immediately, is by a ravine—a sort of gorge or chine worn out by the water from the spring-head above and disintegrating rains throughout the long ages. They find it steep as a staircase, though not winding as one; instead, trending straight up from its debouchment on the plain to the summit level, between slopes, these with grim, rocky façade, still more precipitous. Down its bottom cascades the stream—a tiny rivulet now, but in rain-storms a torrent—and along this lies the path, the only one by which the Cerro can be ascended, as the gambusino already knows. ”
