254 x 195 mm. A view showing the mud lake, dotted with craters of mud and with steam rising from the hillside behind. In a reproduction of this print in Hochstetter (1875), the steam rising from the hills has been retouched to make it more visible:
'The bottom of the ravine consists chiefly of mud in a fluid state ... farther on are numerous small mud cones, from two to five feet in height, some of which, like miniature volcanoes, throw up hot mud from their craters, with a deadened, rumbling sound'.
