VII. Notes on the structure of some rocks from the andes of ecuador, collected by E. Whymper. No. IV. Carihuairazo, Cayambe, and Corazon
I have been favoured by Mr. Whymper with some short notes on the structure and physical features of the three volcanic mountains whose rocks are investigated on this occasion, and have prefixed them to my lithological descriptions. It is remarkable what a general uniformity there is in the products of these summits of the Equatorial Andes, and this, as Mr. Whymper informs me, was so obvious that he made but small collections from the mountains which were visited during the latter part of his journey. Carihuairazo . “This forms the northern part of the massif of Chimborazo. It is separated on its south side from its great neighbour by the depression called Abraspungo (14,479), and its northern slopes extend almost to the town of Ambato (8,500). The road to Quito winds round its eastern side, and may be considered to mark its boundaries in that direction.
