The road through the Catuaro jungle resembles the descent through the Santa María mountain; the difficult parts are given odd names. You follow a narrow channel, scooped out by torrents and filled with a fine, sticky clay. In the steep parts the mules sit on their rumps and slide downhill. This descent is called Saca Manteca because the consistence of the mud is like butter. There is no danger in this descent as the mules are very skilled at sliding.
