R.K. Selander, 1954 19 Tonala to Tres Picos, Chiapas, Mexico April 12 Foreston hills is in leaf - but apparently just starting - Many totally bare elements. Flat land vegetation is the same I am sure. There is a low pass in the hills over the other large sandy hill is plainly visible. (Our map seems correct so far.) This apparently where Rio la Polka to passes. We crossed it - it was dry. A few amates, palme, guanacastes around the town which is located immediately adjacent to the Rio la Polka. The land surrounding the town is the typical low deciduous forest - this vegetation type seems uniform and extensive. Many small mango trees around houses, Much ti to poste on the hills in the deciduous forest vegetation especially in arroyos. Large areas of decid. forest burned for farming in the lowlands - whole area probably has been cleared several times. Just beyond town hills come to water; less than 2 blocks of the water 'for as for a mile or so there is no flat land as the hills approach the water edge 2-3-4 blocks close.
