area is alwavs present between llie base of the range an<1 the 

 meadow lands, and this is shown in the forej^roiind, while on 

 the right a line (^f willows and cottonwoods marks the conrse of 

 Cave creek. In the background is shown the sage brush cov-

Canij) was established at the ranch of Dr. Hager, about a 

 mile below Cave creek, and three days were spent exploring the 

 region. The dry sage brush area along the base of the ridge 

 yielded CJunopodiiDn Icptophyllnm, Mysorrhiza midtiflora, Ly- 

 godesmia spiuosa, (httierresia diversifolia and Solidago pulcher- 

 rivia, while in the meadows in soil containing but little alkali 

 the following were found: 



Carex nebrascensis Anthopogon detonsa 



Scirpus occidentalis Mimulus Langsdorfii 



Astragalus nitidus Lactuca pulchella 



Chamaenirion angustifolium Aster oxylepis 

 Glaux maritima Solidago missourieiisis 



Amarella strictif^ora 



Several alkaline areas produced by far the greater number 

 of species found in the low laud. They were: 

 Triglochin maritima Nitrophila occidentalis 



Agropyron tenerum Sarcobatus vermiculatus 



Distichlis dentata Rumex persicarioides 



Elymus triticoides Radicula obtusa 



Spartina gracilis Ivesia Kingii 



Sporobolus filiformis Sium cicutaefolium 



Scirpus campestris Heliotropium spathulatum 



Atriplex truncata Crepis glauca 



Chenopodium glaucum Brachyactis frondosa 



Dondia occidentalis Pyrrocoma subviscosa 



On August 20th the ridge above camp was ascended to 9300 

 feet, the line of least resistance in the shape of a canyon being 

 followed up to 7300 feet. In fact, there are not many places 

 in the immediate vicinity where an ascent can be easily made, 

 on account of the precipitous rim rocks or terraces.
