Synopsis 



The 1998 photopoint is slightly 

 below and south of the original 

 photopoint. This change was 

 necessary because the original 

 point moved in conjunction with 

 a large soil slump arising from 

 the irrigation of cropland on the 

 adjacent upland bench. The 

 original "side creek bottom" is 

 Warm Spring Creek, not the 

 Judith River mentioned by 

 Phillips in 1959. Shizachyrium 

 scoparium has continued to 

 decline along the upland, 

 whereas a more mesic vegetation 

 complex, dominated by Spartina 

 pectinata, has developed in the 

 bottomlands in conjunction with 

 the construction of a small 

 reservoir after 1959. Artemisia 

 cana has also declined in abun- 

 dance in foreground uplands, 

 whereas Juniperus scopulorum, 

 Amalanchier alnifolia, and 

 Prunus virginiana has increased 

 dramatically along the north- 

 facing hillside (right side of 

 photo). Pinus ponderosa has 

 continued to increase in abun- 

 dance on the distant mountain.
