Two parallel trap lines were established on October 4, 1961, in the area immediately south of Far View Ruins (Fig. 1). In altitude, latitude and geographical configuration the area is similar to that trapped in the Morfield burn, but the Chapin Mesa site had not been burned. Canopy vegetation is pinyon-juniper forest. A dense understory was made up of _Amelanchier utahensis_ (serviceberry), _Cercocarpos montanus_ (mountain mahogany), _Purshia tridentata_ (bitterbrush), and _Quercus gambelii_ (Gambel oak). The ground cover consisted of small clumps of _Poa fendleriana_ (muttongrass), and _Koeleria cristata_ (Junegrass), intermingled with growths of one or more of the following: _Artemisia nova_ _Solidago petradoria_ _Sitanion hystrix_ _Astragalus scopulorum_ _Lupinus caudatus_ _Eriogonum alatum_ _Penstemon linarioides_ _Eriogonum racemosum_ _Eriogonum umbellatum_ _Polygonum sawatchense_ _Amelanchier utahensis_ _Purshia tridentata_ _Comandra umbellata_ Seeds of _Cercocarpos montanus_ covered the ground under the bushes in much of the trapping area, and large numbers of juniper berries were on the ground beneath the trees. Individuals of _P. truei_ and _P. maniculatus_ were caught in this area (Table 1). Several deer, rabbits, one coyote, and numerous birds were seen in the area. No reptiles were noticed, but they were not searched for. A mountain lion was seen in this general area two weeks after trapping was completed. _West of Far View Ruins_ Three pairs of traplines were run west of Far View Ruins in an area comparable in vegetation, altitude, general topography, and configuration to the area previously described. The elevations concerned are typical of the middle parts of mesas throughout the park. This area differs from the trapping area south of Far View Ruins and the one on Morfield Ridge in being wider and on the western side of the mesa. The woody understory was sparse in most places, and where present was composed of _Cercocarpos montanus_, _Purshia tridentata_, _Fendlera rupicola_ (fendlerbush), _Amelanchier utahensis_, _Quercus gambelii_, and _Artemisia tridentata_ (sagebrush). The herbaceous ground cover was dominated by _Solidago petradoria_ (rock goldenrod), and grasses--including _Poa fendleriana_, _Oryzopsis hymenoides_, and _Sitanion hystrix_. Other herbaceous species were as follows: _Echinocercus coccineus_ _Achillea millefolium_ _Aster bigelovii_ _Wyethia arizonica_ _Lepidium montanum_ _Lupinus caudatus_ _Yucca baccata_ _Linum perenne_ _Eriogonum racemosum_ _Eriogonum umbellatum_ _Polygonum sawatchense_ _Delphinium nelsonii_ _Penstemon linarioides_
