JPMycs 1974 Journal (1,18) Estancia Medaland, 35 Km S. of Juancho by road, Pdo de Madariaga, Provincia de Bs Aires, Argentina. 15 October [illegible](cont'd) Although not represented in this cross-section, a typical formation in the 'ridge' is a depression much the converse in dimension to the slight rise down in [illegible] to the W of the tower. They are shallow - less than 3 m deep, usually fairly ground and perhaps 100-150 m across maximum. Vegetation now is all under 5 cm and the vast majority is less than 3 cm high. I have taken plants for ID. Most are grasses, there is Trifolium [illegible] in abundance. Thistles have not yet begun to regenerate. An impossibly high density of leaf-cutter ants covers the field, and there are many clumped groups of armadillos digging. I have also taken for ID various insects which we have found - most coleopterans and some Leptidopteran larvae. 2 scorpions. Many grubs are in the substrate, and in fact they appear to be common golden and Oreophalus food - see appendix. Grid 16a lies 25 m NW of the base of the tower; 16b lies 25 m NE : SW ↑ [illegible] 16a [illegible] [illegible] [illegible] Each grid 25 x 25m total (i.e. 625 m²) with subunits of 5x5m. I will be pulling in 16c and 16d and 16a, which can lie SE + SW of the tower, and he built the same as 16a and b. Also, I plan to add grid 17, a series of 75x75m units composed of 25x25 subunits (i.e. the same as 4a). 17a, 17b, 17c etc. [illegible] to [illegible] Estancia Medaland, Pdo de Madariaga, Provincia de Bs Aires, Argentina 17 October 0700 began draining out towards 2nd windmill, taking microdata en rock. Temp ~10°C, clouds ~80% consisting of low, dense but thin (a high fog bank) cumulus, light S wind. Everywhere on the ground are puddles as a result of 22 mm of rain (actually drizzle) which fell from the afternoon of the 15th until yesterday evening. Although this makes an accumulation of over 30 mm in 3 days, the campo does not show the effect of the rain as much as we are hidden in camp while the wind blew - hoped that it would. Many wildflowers are starting to pop up in the grass fields - it has turned a rich green. During the morning [illegible] was able to take 8 points -
