Hendrickson 1950 Journal Nov. 8 Villavieja, 1400 ft., Huila, Colombia, S. A. at its widest point. My guess is that about 10 ft. was its maximum elevation above the river level on this day. The river is a muddy torrent and its level changes radically depending on rains which augment its flow. The river has - in most parts (so far as I could determine) a cobble bottom, and cuts between clay banks thickly interwoven with roots. It is bordered by a zone of riverside woodland, broken in many spots by banana fields of varying sizes. The island bears a dense, tangled woodland in some spots, in other portions it is covered by park-like grassland, with scattered large trees and 3' - 5½' coarse grass. There are several fields of bananas and other tree crops on the island, and apparently some people live in huts on the island - at least temporarily at certain seasons. A herd of cattle is kept there, also. There are many sand and mud bars at the edges of the island (mainly W side and N end), and bushy thickets of willow- like small trees grow in some of these
