Synopsis 



Earlier photos indicate heavy 

 grazing. However, 1998 photos 

 reveal grazing intensity had been 

 dramatically reduced, resulting 

 in a grass-dominant complex of 

 Agropyron smithii, Stipa comata, 

 and Stipa viridula. Furthermore, 

 the position of the large rocks 

 has remained constant, but an 

 abundance of Melilotus officinalis 

 in 1999 caused their presence to 

 be less conspicuous because of 

 the taller vegetation.
