First Retake and 

 Description 



June 19, 1959. W.S.P., 

 No. 2079. 



Dr. Shantz took a 180° 

 panorama from this point 

 and made a rather complete 

 list of the species present at 

 this rock. The main grasses 

 are Agropyron spp. and Stipa 

 viridula. In addition Dr. 

 Shantz listed the following 

 plants as growing in this 

 area: Agropyron spp., Stipa 

 viridula, Cirsium plattense, 

 Grindelia squarrosa. Phlox 

 spp., Vicia americana, Iva 

 axillaris, Aster spp., 

 Lesquerella spp.. Erysium 

 asperum, Comandra pallida, 

 Opuntia polycantha. Bahia 

 oppositifolia, Helianthus 

 spp., Atriplex canescens. 

 Allium reticulatum, and 

 Plantago purshii. In the 

 pictures of this area the 

 most noticeable changes 

 between the old and the new 

 is the increase in the 

 amount of Prickly Pear in 

 the new pictures (from 

 Phillips 1963, p. 119).
