The emerging seasonal subdivisions in the rural mountainous regions of Kane County was the focus of this study . A native of Kanab, county seat, the author has been in a position to witness the development of these projects. The desired purpose of the study was to ascertain the degree of involvement of local government and to indicate problems, their solutions and consequences. The problems encountered in analyzing these developments are basically those that must be faced by any new emerging community. No individual study was discovered that dealt with the specific locality under consideration. Of very recent origin, the developments have provided little time for in depth analysis. The absence of related studies has offered the author more personal contact with involved individuals than might otherwise have been the case. The author attempted to view the subdivisions as seen by both subdivider and governing official. Written questionnaires, personal interviews and informal discussions, on-site inspection of subdivisions , vis its to county offices, letters, and telephone interviews have provided the background material for this thesis. The study resulted in the following observations: 1. Local government must engage in long-range planning to effectively deal with the problems of the subdivisions. 2. Failure to adequately prepare now will necessitate far greater expenditures in future county operations. 3. As the problems continue to grow, so, too , will the cost of their eradication or containment. 4. Intergovernmental cooperative studies appear to be a logical method of determining overall effect of the problems. 5. Restructuring of local government may become necessary.

This thesis is a study of vertebrate distribution in relation to certain habitats in cetral Kane County, Utah. Four areas were trapped, two in a sagebrush community and two in a grassland community. Oryzopsis hymenoides (Roem & Shult.) Ricker, Hilaria jamesii (Torr) Benth., Ephedra torreyana S. Watts and Guttierrezia sarothrae (Purah.) Britt and Rusby, were the dominant plants in the grassland community. The dominant plants in the sagebrush community were Artemisia tridentata Nutt., and Hilaria jamesii (Torr.) Benth. Dipodomys ordii cupidineus Goldman was the most common mammal trapped in both communities. Peromyscus maniculatus sonoriensis (LeConte) was trapped most often in the sagebrush community, but rarely taken in the grassland community. Reithrodontomys megalotis megalotis (Baird), was trapped most often in the grassland and only rarely in the sagebrush community. This cricetid seemed restricted to a habitat that offered a large amount of shrub and grass cover. Perognathus parvus trumbullensis Benson, seemed to be restricted to the sagebrush community. This was the only species that was not trapped in the grassland community. Perognathus longimembris arizonensis Goldman, on the other hand seemed to be restricted in central Kane County to the grassland community, because it was the only mammal that was not caught in the sagebrush community. Perognathus formosus domisaxensis Cookrum, appears to be the ecological equivalent on the Cockscomb Ridge of P. parvus in the sagebrush community and P. longimembris in the grasslands. From the data collected, Onychomys leucogaster melanophrys Merriam, appeared to be limited in distribution to the number of available invertebrates near the trapping transect. Most of the mammals that were trapped on the west side of the ridge, in the sagebrush community, appeared to be darker in color than those from the east side of the ridge. Thomomys umbrinus howelli exhibited a greater color contrast between the two communities than any other species. Closer examination of the skulls of these mammals revealed a difference in the width of the basioccipital between those caught on the west side of the ridge and those caught on the east side. The range of Crotalus viridis lutosus Klauber was extended east from the Cockscomb Ridge to the Paria Plateau. The range of Eutamias dorsalis utahensis Merriam was extended south past Catstairs Canyon.

The sand dunes lying ten miles northwest of Kanab in Kane County, Utah, support a sparse plant cover with four species dominating the vegetation: Psoralea stenostachys, Sophora stenophylla, Oryzopsis hymenoides, and Wyethia scabra var. attenuata. Of these Psoralea and Wyethia are endemic to the dunes or to a limited area which includes the dunes. The pineer species gain a start in the valleys between dunes and occupy the area only until sand covers them or until sand is blown away from their roots. Stabilization of the soils is not permanently in the interdune valleys and the dunes continue to wander. The low fertility of the soils, the low moisture content, the extremes of temperature, light, and other environmental factors limits the number of individual plants which can occupy the dunes. The region will continue to have actively moving dunes until major climatic changes occur permittimg a denser plant cover which would tend to stabilize the sands.

In the Paria Plateau area of northern Arizona and southern Utah the Chinle formation of Upper Triassic age consists of a thick series of Ienticular sandstone, siltstone, claystone, and limestone. The series thins northwestward from about 900 feet at Lees Ferry, Ariz., to about 800 feet at Paria, Utah. Four members of the Chinle formation are recognized—1) the basal Shinarump member composed of conglomeratic sandstone and subordinate shale, 2) a unit, herein named the Lowery Spring member, composed of sandstone and mudstone, 3) the Petrified Forest member composed of bentonitic siltstone and claystone and thin sandstone, and 4) the Owl Rock member composed of cherty limestone and calcareous siltstone. Only the Petrified Forest member is present at all localities in the Paria Plateau area. The Shinarump member was deposited in topographic low areas on an erosion surface and its distribution is irregular. The Lowery Spring and Owl Rock members grade and pinch-out toward the northwest and are not present at Paria, Utah. The upper contact of the Chinle formation is locally unconformable. The three lowermost members were deposited on a broad, flat plain between the Cordilleran geosyncline and highlands to the southeast. In Owl Rock time the rising Cordilleran geanticline cut off the north-westward drainage of Chinle streams and a depositional basin trending southwest was formed.
