J Pilnyers 1974 Journal 28 August (cont'd) Estancia Medaland, 35 Km S. of Juancho by road, Dpto de Madariaga, Provincia Bs. As., Argentina 30 m wide depression extending 1500 m to the S and beginning just S of the Medaland border. It is dammed at the S end, and which may explain in part why it continues to have water. Most of it is now saturated mud, with a few patches of Tule and/or Salamanca, but towards the S end there is extensive water. Many shorebirds were present (see list below). I was accosted there by a poon, to whom I explained what I was doing (I was from Atlantida), and he had obviously heard of me.
