Why take your kids to the neighborhood playground, when you can visit a playground that inspires their sense of geologic adventure? Devils Playground is not your ordinary community playground, but a wonderland of granitic rock weathered into fantastic forms and weird shapes. Occupying an assortment of Bureau of Land Management, state, and private land in the Bovine Mountains, Devils Playground is a relatively unknown geologic curiosity found in a remote corner of northwestern Utah. Devils Playground is situated in the physiographic region known as the Great Basin province that extends across western Utah, Nevada, and to the Sierra Nevada Mountains in eastern California. The area is composed mostly of granitic rocks of the Emigrant Pass intrusion. A combination of granitic rock, faulting, and weathering under a semiarid climate created favorable conditions for the creation of Devils Playground. Desert plants such as sagebrush,Utah juniper, pinyon pine, Mormon tea, and cheatgrass are common throughout the area.

The chain of Rocky Mountains extending south from Canada through western Montana. Wyoming, Colorado and into northern New Mexico produce a series of butterflies which are at prespnt referable under an anicia-brucei classification. Various races from this supposed parental stock are found in southwestern Colorado, Utah, the Great Basin of Nevada and elsewhere with members of the clan branching down into New Mexico. For several years I have been hoping to find representatives of this group reaching over into the Sierra Nevada Mountains of California. In 1927 when on Alta Peak in Sequoia National Park, I took two males and in 1928 Mr. Walter Ireland captured four females in the same locality which I find to be closely related to the above mentioned breed.

REVISION OF NORTH AMERICAN AGABUS LEACH (COLEOPTERA: DYTISCIDAE): LUTOSUS-, OBSOLETUS-, AND FUSCIPENNIS-GROUPS

AbstractSpecies of Agabus of the lutosus-, obsoletus-, and fuscipennis-groups, as defined by Larson (1989), are revised. Members of the lutosus- and obsoletus-groups are restricted to the Cordilleran and Great Plains regions of temperate western North America. Within this region, the species of each group are largely parapatric. Three species are assigned to the lutosus-group: A. lutosus LeConte along the Pacific Coast; A. griseipennis LeConte in the Great Basin, Rocky Mountain, and Great Plains regions; and A. rumppi Leech in the southern deserts. Agabus lutosus and A. griseipennis hybridize in the Pacific Northwest; A. lutosus mimus Leech is synonymized with A. lutosus. The obsoletus-group contains five species: A. obsoletus LeConte, A. morosus LeConte, and A. ancillus Fall along the Pacific Coast and the Sierra Nevada Mountains; A. hoppingi Leech in the Sierra Nevada Mountains; and A. obliteratus LeConte, containing two subspecies, A. o. obliteratus and A. o. nectris Leech, new status, with a wide range including the Great Plains and Cordillera but not reaching the Pacific Coast. The four species of the fuscipennis-group, A. ajax Fall, A. coxalis Sharp, A. fuscipennis (Paykull), and A. infuscatus Aubé, are boreal and all except A. ajax are Holarctic. Agabus coxalis is restricted to northwestern North America, the other three species are transcontinental.For each species the following information is provided: synonymy, description, and illustrations of taxonomically important characters; notes on relationships, variation, distribution, and ecology; and a map of North American collection localities. Group diagnoses and keys to the species of each group are presented. A correction to the key to species groups of North American Agabus (Larson 1989) is made with the addition of a couplet to include the obsoletus-group. Lectotypes are designated for A. discolor LeConte and A. obliteratus LeConte.

Oil Tank

On a cool, crisp winter afternoon in a California desert, at the foot of the eastern slope of the Sierra Nevada Mountains, a crowd of more than two thousand people gathered. Some were curious; more were angry. Before all of them, standing on an oil tank with a microphone and loudspeaker, forty-seven-year-old Joseph Y. Kurihara shouted angry words of defiance. Referring to the generally despised Fred Tayama, who was assaulted the night before, Kurihara bellowed, “Why permit that sneak to pollute the air we breathe? … Let's kill him and feed him to the roving coyotes! … If the Administration refuses to listen to our demand, let us proceed with him and exterminate all other informers in this camp.”
