Ascending Between the strips of forest which follow the streams are areas of savannah (coarse, bunchd, grass in 2'-4' clumps, with semi- (4"-12") grass between the clumps). Ascending the almost plane E slope of the foothills, we passed over black lava rock supporting a fairly dense growth of grass. The plane E surface of the foothills slopes at about 30°. At the crest of the foothills one stands at the top of steep cliffs falling away to savannah and the forest along the Rio Dujéjar.
